B2G User Interface Manual

2.4.1   The Power Switch

The Power switch is the slide switch near the back of the right side. It's off position is toward the front, and its on position is toward the back.

If the system is shut down, then:

• Switching it on boots the device. You should hear one short beep. If, instead, you hear three short beeps then the battery is too low and the device won't boot. In this case, switch it back off, and then charge the battery for a while before trying again.
• Switching it on while holding VolumeDown boots the device into Recovery Mode.

If the system is running, then:

• Switching it off puts the system to sleep.
• Switching it on wakes the system up.

When the system is either booted or woken up, the following settings are reset to their default values:

• The braille display is enabled (see Disabling the Display) if speech is disabled.
• The typing mode is set to Regular Text (see Typing Modes).
• Highlighted typing is turned off (see Typing Highlighted Characters).

2.6.1   The Reset Button

The Reset button is hidden within a very small, round hole on the bottom. If the device is turned over, front to back, the hole is at about the eight o'clock position relative to, and very close to, the foot nearest to the Power switch. A thin, round, blunt-tipped object, like the end of an unbent paperclip, should be used to press it.

To reset the B2G, slowly insert the paperclip into the hole, keeping it almost vertical but leaning slightly toward you. You should feel a soft click, and also hear a long, high-pitched beep. You only need to press gently. If it feels like you're pressing against a hard surface then you've missed the button.

2.6.2   The Removable Cover

There's a removable, rectangular, plastic cover in the middle of the bottom. To remove it:

1. Turn the device over so that its bottom is on top.
2. Press gently down on the cover, and then slide it toward the side where the Power switch is.
3. Lift the end of the cover that's toward the side where the earphone jack is.

Be careful after you've removed the cover because the underside of a circuit board will be exposed.

Removing the cover is how to gain access to the following:

• The Micro-SIM card slot is in the corner that's toward the front and toward the side where the Power switch is. To gain access to the actual slot, slide its cover slightly toward the front and then lift the end of it that's toward the back. As with most SIM card slot covers, its hinge is fragile so be gentle.
• The Serial Port is in the corner that's toward the back and toward the side where the Power switch is. It's a 10-pin (2x5) male connector that can be used by the B2G developers to perform low-level system maintenance.

3.2.1   Long Press Mode

A secondary action may be bound to a key combination. A key combination's secondary action is executed if all of its keys are held until the long press timeout expires. The long press timeout is half a second.

This mode is enabled by default. Pressing Forward+Dot6 enables it, and pressing Backward+Dot3 disables it.

3.2.2   One Hand Mode

One Hand Mode has been designed to make the B2G easy to use by those who only have the use of one of their hands. It's disabled by default. Pressing Dot8+Forward enables it, and pressing Dot7+Backward disables it. Both of these key combinations were chosen so that they can be reasonably easily pressed with a single hand.

When One Hand Mode is enabled, each dot key of a combination may be pressed separately. For those whose operable hand is sufficiently functional, pressing more than one key at a time is supported. Press Space after all of the keys have been pressed to indicate that the combination has been fully entered. The Space key itself isn't included within the combination. If the combination does contain the Space key then an additional Space must be pressed, by itself, first.

So:

1. If Space is part of the combination then press it, on its own, first.
2. Press the dot keys of the combination either separately or in groups.
3. Press Space to indicate that the combination has been fully entered.

To type a space (which is a key combination without any dots), simply press Space twice (with no dot keys in between). There's a quick way to type a space immediately after typing a character (except after a space). After pressing all of the dots that represent the character, followed by Space to complete that combination, quickly press Space again (just once). The amount of time that you have to do this (before pressing Space reverts to starting a new combination that includes it) can be customized via the Space Timeout setting (which defaults to 1 second).

If Space is pressed at the same time as at least one other key then all of the pressed keys (including Space) are added to the current combination, and the combination is then considered to be complete. This allows users who are able to press Space together with other keys to navigate more quickly.

Pressing any of the other B2G keys:

• a panning key (Forward, Backward)
• a D-Pad key (Up, Down, Left, Right, Center)
• a cursor routing key
• a volume key

also signals the completion of the current key combination. In this case, you don't press Space to indicate that you're done. That key, as well as all of the other keys that are also pressed at the same time, are included within the current combination.

While this feature allows for natural and efficient screen navigation, it also means that a combination involving more than one of these other keys can't be used when in One Hand Mode. Additional alternate combinations have been defined, therefore, in order to mitigate this restriction. They are:

If you don't press any keys for a while after having started a combination then that combination is automatically cancelled and you need to start over. The amount of time before a combination is cancelled can be customized via the Pressed Timeout setting (which defaults to 15 seconds).

3.3.1   Typing Modes

Space+Dots78+t (dots 2345) displays a message (see Messages) that confirms which typing mode is currently being used.

Regular text is the default, and is used for Directly Typing Regular Text.

Actual cells is used for Directly Typing Actual Braille Cells.

Either booting the B2G or waking it up (see The Power Switch) automatically resets the typing mode to regular text.

3.3.2   Typing Highlighted Characters

The following highlighting styles are supported for typing:

Bold

• Press Space+Dot8+b (dots 12) to turn it on.
• Press Space+Dot7+b (dots 12) to turn it off.

Italics

• Press Space+Dot8+i (dots 24) to turn it on.
• Press Space+Dot7+i (dots 24) to turn it off.

Strike-through

• Press Space+Dot8+s (dots 234) to turn it on.
• Press Space+Dot7+s (dots 234) to turn it off.

Underlining

• Press Space+Dot8+u (dots 136) to turn it on.
• Press Space+Dot7+u (dots 136) to turn it off.

Pressing Space+Dots78+h (dots 125) displays a pop-up (see Pop-ups) that lists the highlighting styles that are currently active.

Press Space+Dot7+h (dots 125) to turn all of these highlighting styles off. Either booting the B2G or waking it up (see The Power Switch) also turns them off.

Each highlighted character that you type will be flagged by The Selection Indicator. You can verify that a character has been highlighted correctly by holding Dot3 while pressing the cursor routing key associated with it.

3.3.3   Typing a Control Character

In order to type a control character, press Space+x (dots 1346) immediately before the letter or special symbol that represents it (see ASCII Control Characters). For example, in order to type a tab (which happens to be control I), press Space+x and then immediately type the letter i.

The letter or special symbol must be typed within two seconds.

3.3.4   Indirectly Typing Any Character

Any character can always be indirectly typed, even if directly typing it isn't possible:

• Its braille representation hasn't been defined.
• You don't know its braille representation.
• It's represented in braille by either just dot 7 (the Backspace key) or just dot 8 (the Enter key).

In order to indirectly type it, press Space+u (dots 136). This brings up a prompt (see Prompts) with the following header:

Unicode> U+

U+ is the conventional prefix for the hexadecimal value of a Unicode character. The prompt allows you to enter up to four hexadecimal digits - 0 through 9 and A through F (either upper or lower case). Leading zeroes may be omitted. The Unicode values of characters are, of course, beyond the scope of this document.

The digits you enter may be freely edited, e.g. the cursor can be moved, any digit may be deleted, a new digit may be inserted, etc. In other words, making corrections doesn't require backspacing and retyping. When you're done, press Enter.

If no digits have been entered yet (or if they've all been deleted) then you'll only see the header. If, however, at least one digit has been entered then the character represented (so far) by the digit(s) is displayed just to the right, and that character's formal name is displayed on the next line.

To illustrate, let's see how a lowercase s would be indirectly typed. It's Unicode value is U+0073. In order to keep this example simple, let's skip the two leading zeroes.

3.3.5   Adding/Removing Diacritical Marks

One way to add or remove a diacritical mark (an accent) from a letter is to retype that letter using the corrected braille representation. This is the most natural way to do it for those who are using an appropriate braille code and are familiar with it. For other braille users, however, this seemingly simple and common literary endeavour can be rather daunting. It may even be impossible if the braille code being used doesn't support it.

The B2G User Interface provides a menu-based way to add and remove diacritical marks that can be easily used by anyone. It modifies the character that's immediately to the left of the cursor indicator so that the most common case, typing a letter and then adding diacritical marks to it, can be performed in a natural and intuitive way. See Supported Diacritical Marks for a list of the diacritical marks that the B2G User Interface supports.

To add a diacritical mark to the character, press Space+Dot8+m (dots 134). This presents a pop-up (see Pop-ups) that lists all of the diacritical marks that may be added to the character. Navigate to the one that you'd like to add, and press Center. Pressing Enter will cancel the operation without modifying the character.

To remove a diacritical mark to the character, press Space+Dot7+m (dots 134). This presents a pop-up (see Pop-ups) that lists all of the diacritical marks that are currently on the character. Navigate to the one that you'd like to remove, and press Center. Pressing Enter will cancel the operation without modifying the character.

There are a few ways to find out which diacritical marks are currently on a character:

• Place the cursor indicator immediately to the right of the character and then press Space+Dot7+m (dots 134) - the process (documented here) to remove a diacritical mark. Read the list of diacritical marks that are currently on the character, and then press Enter to cancel the operation. This method won't work if there are no diacritical marks on the character.
• Hold Dot7 while pressing the cursor routing key behind the character. See Identifying an Unrecognized Character for details.
• Place the cursor indicator on the character and then press Dots36 to have it spoken. See Editing with Speech for details.

3.3.6   Typing Emoticons

Emoticons are sequences of basic characters (commonly used within emails, text messages, etc) that depict emotions. For example:

• :-) for a smile (happy face).
• :-( for a frown (sad face).

The B2G User Interface offers a menu-based way to type an emoticon. Pressing Space+e (dots 15) presents a list of emoticon descriptions within a pop-up (see Pop-ups). Pressing Center on the desired description types its corresponding emoticon. Spaces are added to either side of the emoticon, as needed, to ensure that it's separated from the surrounding text. Pressing Enter will cancel the operation without typing an emoticon.

See Supported Emoticons for the list of emoticons that the B2G User Interface supports. Some literary braille codes might not work well with some emoticons - for example, those that don't allow for a colon at the beginning of a word. Likewise, some speech voices may behave unexpectedly - for example, they may:

• speak a different description
• spell out the individual characters
• say nothing at all

3.5.1   Messages

Messages are used to give you feedback for significant events. These include (but aren't limited to):

• The successful changing of a setting.
• The timeout of a partially entered request, e.g. the control modifier has been pressed but the (then required) letter or special symbol hasn't been typed quickly enough (see Typing a Control Character).

A message is a single-line, read-only dialog. No navigation may be performed within it. It remains on the braille display for two seconds.

3.5.2   Pop-ups

Pop-ups are used to present user-requested data as well as important system information. This includes (but isn't limited to):

• The arrival of an Android notification.
• The description of a character (see Identifying an Unrecognized Character).
• The values of various status indicators.
• An Action Chooser.

A pop-up is a multi-line, read-only dialog. Normal navigation may be performed within it. Dismiss it by pressing Enter. It's automatically dismissed if no navigation operations have been performed within it for 30 seconds.

3.5.3   Prompts

Prompts are used to request information from you. This includes (but isn't limited to):

• Requesting the value of a Unicode character (see Indirectly Typing Any Character).
• Requesting the text to search for within the current screen element (see Finding Text within the Current Screen Element).

A prompt is a read-write dialog. Normal navigation and editing may be performed within its response area. Press Enter once the requested information has been entered.

The prompt's header and response area are always on the first line. The B2G User Interface may add helpful information to the rest of the first line and/or to additional lines.

The response to a prompt is remembered. The response area of a prompt is initially empty, but, from then on, it's initialized to the previous response entered for that prompt. The remembered response is selected (see Text Selection) so that it can be easily replaced.

3.5.4   Action Chooser

An action chooser is a special kind of pop-up (see Pop-ups) that presents you with a list of actions and lets you choose which one to perform. For places where it's used, see:

• Ways to Learn
• Shortcuts to Useful Android Screens

Each line of the dialog shows one of the available actions. It contains the name of the action, the key combination that performs it (when not within the chooser), and a summary of what it does. Press Center to perform it from within the chooser. Press Enter to leave the chooser without invoking an action.

4.5.1   Shortcuts to Useful Android Screens

The following shortcuts to useful Android screens are provided:

Space+p (dots 1234)

Go to the Power Off screen.

Space+? (dots 1456)

Go to the currently registered assist app. The default is Google Now.

4.5.2   Shortcuts to Other B2G Applications

The following shortcuts to other B2G applications are provided:

Space+ed (dots 1246)

Go to the NBP editor.

Space+! (dots 2346)

Go to the NBP IPAWS monitor.

Describing how any of these applications work is, of course, beyond the scope of this document.

4.6.1   The On-screen Monitor

An on-screen monitor that shows what's on the braille display can be enabled from the Braille Settings screen. It shows both the braille cells and the text.

4.6.2   Adjusting the Dot Firmness

The firmness of the braille dots can be adjusted from the Braille Settings screen.

4.6.3   Disabling the Display

The braille display is enabled by default. It can be disabled by pressing Backward+Dot1, and reenabled by pressing Forward+Dot4. Either booting the B2G or waking it up (see The Power Switch) also reenables it if speech is disabled. Braille can't be disabled while speech is disabled.

4.7.1   Adjusting the Speech

Adjusting the Volume:

• Press Dot1+VolumeDown for softer.
• Press Dot1+VolumeUp for louder.

The speech volume is set relative to the system volume. If, therefore, the speech volume is set as high as it'll go but it still sounds too soft then try increasing the system volume (by pressing VolumeUp by itself).

Adjusting the Rate:

• Press Dot2+VolumeDown for slower.
• Press Dot2+VolumeUp for faster.

Adjusting the Pitch:

• Press Dot3+VolumeDown for lower.
• Press Dot3+VolumeUp for higher.

Adjusting the Balance:

• Press Dot4+VolumeDown for more left.
• Press Dot4+VolumeUp for more right.

4.7.2   Reading with Speech

• To interrupt what's currently being spoken, press Dot1+Left.
• To hear all of the current line, press Dot1+Right.
• To hear all of the current screen element, press Dot1+Center.
• To hear just what's before the start of the braille display, press Dot1+Up.
• To hear just what's on and after the braille display, press Dot1+Down.

4.7.3   Editing with Speech

• To have the current character spoken, press Dots36. If text has been selected then all of the selected characters are spoken.
• To have the current character spoken phonetically, long press Dots36. Long Press Mode needs to be enabled. If text has been selected then all of the selected characters are spoken phonetically.
• To have the current word spoken, press Dots25. If text has been selected then the selected text is spoken.
• To have the current word spelled, long press Dots25. Long Press Mode needs to be enabled. If text has been selected then the selected text is spelled.
• To have the current line spoken, press dots14.
• To have the current line spelled, long press dots14. Long Press Mode needs to be enabled.

When a character is spoken (or when text is being spelled), the prefix cap (meaning capital) is added if it's an uppercase letter. Additionally, if the character has any diacritics (accents) then each of their names is spoken after it (see Supported Diacritical Marks for details). For example:

• The letter É (an uppercase E with an acute accent) is spoken as "cap e acute".
• The letter ǘ (a lowercase u with diaeresis and acute accents) is spoken as "u diaeresis acute".

When a character is spoken (or text is being spelled) phonetically:

• English letters are spoken as corresponding English words so that they can be easily differentiated from one another (see English Phonetic Alphabet for details). For example, with some text-to-speech synthesizers it may be difficult to discern the difference between b and v. When spoken phonetically, however, it's easy as, respectively, they are Bravo and Victor.
• All other characters are spoken by name.

4.7.4   Customizing What Is Spoken

There are a number of speech settings that can be used to customize how much is spoken. All of them default to on, but each of them can be individually turned off. They are:

Echo Words

Speak each word after it's been fully typed. A word is deemed to be complete as soon as a space is typed.

Echo Characters

Speak each character as it's typed. If characters are typed quickly, e.g. when pasting from the clipboard, then they may be grouped together and pronounced, for example, as a partial word.

Echo Deletions

Speak each character as it's deleted (see Input Areas). The character being deleted is spoken, followed by the word deleted. If characters are deleted quickly, e.g. when deleting a block of selected text (see Text Selection), then they may be grouped together and pronounced, for example, as a partial word.

Echo Selection

Speak changes to the start or end of the text selection. The character at the new position is spoken, followed by the phrase start of selection or end of selection.

Speak Lines

Speak the entire line either when vertical navigation explicitly switches to a new one or when horizontal navigation implicitly wraps to a new one.

4.7.5   Sleep Talk Mode

Sleep Talk Mode leaves speech active while the Power switch is off. This capability is useful when, for example, you'd like to reduce battery drain but still be informed when an important asynchronous event, e.g. the arrival of a notification, occurs.

This mode is disabled by default. Pressing Backward+VolumeUp enables it, and pressing Backward+VolumeDown disables it. Alternate combinations that are usable in One Hand Mode, which use Dot5 instead of Backward, have also been defined.

4.7.6   Differences from Braille Rendering

Speech is rendered differently than braille is in the following ways:

• The [brackets] around screen element descriptions provided by application developers aren't spoken.
• The {braces} around screen element types aren't spoken.
• A space is inserted in between each pair of a lowercase letter followed by an uppercase letter within screen element types in order to improve the way that each implied word is pronounced. For example, SeekBar is spoken as Seek Bar.
• The (parentheses) around screen element states aren't spoken.
• The state of a checkbox (or switch) is spoken as either checked or not checked.

4.8.1   Relevant Settings

The following settings (on The Settings Screen) pertain to the remote braille display:

Remote Display

A checkbox that enables (checked) and disables (unchecked) the remote braille display. It's disabled by default.

Secure Connection

A checkbox that enables (checked) and disables (unchecked) secure Bluetooth connection capabilities. When enabled, the connection is guaranteed to be authenticated and encrypted. It's disabled by default because some systems, Bluetooth adapters, etc (especially older ones) don't support these capabilities. You may need to try both settings.

4.8.2   Baum Key Emulation

The Baum device that the remote braille display emulates has the following keys:

• A cursor routing key immediately behind each of the braille cells.
• Three display keys at each end of the braille cells. The three on the left, from top to bottom, are D1, D2, and D3. The three on the right, from top to bottom, are D4, D5, and D6.
• A standard, eight-dot braille keyboard behind the cursor routing keys. The four on the left, from left to right, are dots 7, 3, 2, and 1. The four on the right, from left to right, are dots 4, 5, 6, and 8. These keys are also known as B1 through B8 (numbered the same way as the dots).
• A five-position joystick in the middle of the front. Its positions are Left, Right, Up, Down, and Press.
• A button on each side of the joystick. The one on the left is B9, and the one on the right is B10.
• Two function buttons at each end of the front. The two on the left, from left to right, are F1 and F2. The two on the right, from left to right, are F3 and F4.
• A button in between dots 1 and 4 named B11.

The B2G's cursor routing keys are always mapped to the Baum cursor routing keys.

The B2G's five-key directional pad is always mapped to the Baum five-position joystick.

The B2G's eight dot keys, as well as its Backward, Forward, and Space keys, are mapped according to one of the following operational modes:

4.10.2   Updating Applications

1. You'll be asked to choose a package downloader. We recommend ES Downloader.
2. When the download is complete, select Open File. You'll then see lots of information about the package. Compare the new version of the package with that of the already-installed one. Select Install if you wish to proceed or Cancel if not.
3. You'll be asked to choose a package installer. We recommend Package Installer.
4. You'll be asked to confirm that you really want to replace the currently-installed version with the new one.
5. You may be asked to confirm that the application should be allowed to perform various privileged system operations.
6. The currently running version will be replaced by the new one. If the application is running then it'll be stopped. If you're updating the B2G User Interface then it'll be restarted, so don't worry if the keys stop responding and the display goes blank for a moment.
7. Click Done to clear the confirmation screen.

4.10.3   System Update

System updates are also known as OTA (over-the-air) updates. They're used to update either the whole Android system or just parts of it.

A system update is a .zip file that contain special meta-data (including an electronic signature).

4.10.4   File Picker

Some of the maintenance operations require you to choose a file. Android refers to the type of application that enables you to choose a file as a file picker.

If you haven't used a file picker yet, or if you haven't yet chosen your favourite one, then you'll be presented with a list of the file pickers that are currently installed on the B2G, and be asked to select the one that the action should be completed with. We recommend ES File Explorer.

Select the one you'd like to use (or just try) by clicking on it, and then click on one of the buttons at the bottom:

Always

This button will make your selection permanent. Only make this choice if you're absolutely sure that you've made the right selection.

Once

This button makes your selection temporary. You'll be presented with this dialog again the next time you need a file picker. Make this choice if you're not sure yet or if you're still trying them out.

4.10.5   Boot Loader

5.3.1   Leaving the Current Screen Element

The following methods may be used to force an immediate, direct move to the start of the next (or previous) screen element:

• Press Space together with Forward (or Backward).
• Long press Forward (or Backward). Long Press Mode needs to be enabled.

5.3.2   Word Wrap Mode

When Word Wrap Mode is enabled, partial words aren't rendered. The rendered portion of the current line begins at the start of a word and ends with the last word that completely fits. Space between words is skipped when panning. Leading space is only rendered at the beginning of a line.

When Word Wrap Mode is disabled, the braille display is always panned by its full length. Space is never skipped when panning. This often results in the rendering of a partial word at the left and/or right end of the display.

This mode is enabled by default. Pressing Space+Dot8+w (dots 2456) enables it, and pressing Space+Dot7+w (dots 2456) disables it.

5.3.3   Reverse Panning Mode

Reverse Panning Mode is designed for those who prefer to read with their right hands while navigating with their left hands. When enabled, the Forward and Backward keys are reversed insofar as navigation is concerned:

• Backward pans to the right, wraps to the start of the next line, moves to the next screen element, etc.
• Forward pans to the left, wraps to the end of the previous line, moves to the previous screen element, etc.

This mode is disabled by default. Pressing Forward+Dot5 enables it, and pressing Backward+Dot2 disables it.

5.3.4   Explicit Panning

The Forward and Backward keys pan right and left according to the current Word Wrap Mode setting. This can make it difficult to read an indented block of related text (a column, a long word, a timestamp, etc).

The braille display can be explicitly panned by pressing a cursor routing key while holding Dot8. This positions the braille display such that the rendered portion of the current line starts with that character.

The braille display can be directly moved to the start of the first line by pressing Space+Dots123, or to the end of the last line by pressing Space+Dots456. These key combinations are the same as those that have been traditionally used to emulate the Control+Home/End keys of a standard keyboard (see Navigating with an External Keyboard).

5.5.1   Physical Keyboard Key Emulation

What each of these combinations does is defined by Android - not by the B2G User Interface - so navigating with them is, unfortunately, not fully compatible with B2G User Interface navigation:

• Navigating with the Panning Keys
• Navigating with the Directional Keys

Android keeps track of the current screen element when these keys are used, and B2G User Interface navigation can't override this. So, for each screen:

• The first keyboard navigation operation is relative to the current screen element.
• Any subsequent keyboard navigation operation is relative to the result of the previous keyboard navigation operation. Intervening B2G User Interface navigation operations won't be considered.
• B2G User Interface navigation operations are always relative to the current screen element no matter which type of navigation was previously used.

5.5.2   Other Traditional Key Combinations

5.7.1   The Enter Key within an Input Area

The Enter key is Dot8. If the input area supports more than one line then this key ends the current line and starts a new one.

• Pressing it when at the start of a line inserts an empty line just above it.
• Pressing it when in the middle of a line splits that line just to the left of the cursor.
• Pressing it when at the end of a line starts a new line just below it.

5.7.2   Deleting Characters

The Backspace key is Dot7.

• If text hasn't been selected then the character just to the left of the cursor is deleted. If this key is pressed when at the start of a line then that line is joined to the end of the previous one.
• If text has been selected then the selected text is deleted.

The Delete key is Space+d (dots 145).

• If text hasn't been selected then the character where the cursor is is deleted. If this key is pressed when at the end of a line then that line is joined to the start of the next one.
• If text has been selected then the selected text is deleted.

5.7.3   Deleting Words

These actions only work when there's a cursor. If text has been selected then they don't do anything.

• Add Dot7 to Space+d to delete the previous word.
• Add Dot8 to Space+d to delete the next (or current) word.

If the cursor is on space then all of that space is also deleted. If the cursor is within a word (not on its first character) then, rather than deleting the previous/next word, these actions delete the start/end of the current word. Here are the specifics:

Pressing Space+Dot7+d (dots 145) deletes the previous word.

• If the cursor is on a word, but not on its first character, then the characters of that word to the left of the cursor are removed.
• If the cursor is on the first character of a word, or if it's on space after a word, then the previous word, along with all the space after it, is removed.
• If the cursor is on space at the start of a line then all of that space is removed.

Pressing Space+Dot8+d (dots 145) deletes the next word.

• If the cursor is on the first character of a word then that word, along with all the space after it, is removed.
• If the cursor is on any other character (except the first) of a word then the characters of that word to the right of the cursor are removed.
• If the cursor is on space before a word then that word, along with all the space before it, is removed.
• If the cursor is on space at the end of a line then all of that space is removed.

5.7.4   Panning within an Input Area

The Forward and Backward keys pan through an input area in the expected way:

• The Forward key pans to the right, and, at the end of each line, wraps to the start of the next one. At the end of the last line it moves to the start of the next screen element.
• The Backward key pans to the left, and, at the start of each line, wraps to the end of the previous one. At the start of the first line it moves to the start of the previous screen element.

Pressing Space+Dots17 pans the braille display such that its first character corresponds to:

• If text hasn't been selected then the cursor's location.
• If text has been selected then the first selected character.

Pressing Space+Dots48 pans the braille display such that its last character corresponds to:

• If text hasn't been selected then the cursor's location.
• If text has been selected then the last selected character.

5.7.5   The Directional Keys within an Input Area

The directional keys move the cursor through the text, one step at a time. They will not leave the input area. The braille display is panned, as needed, such that the cursor is always visible.

The Left key moves the cursor to the previous character. If it's at the start of a line then it wraps to the end of the previous line. If text has been selected then the cursor is moved to just before the first selected character, and the selection is cleared.

The Right key moves the cursor to the next character. If it's at the end of a line then it wraps to the start of the next line. If text has been selected then the cursor is moved to just after the last selected character, and the selection is cleared.

The Up key moves the cursor to the same position on the previous line. If that line is too short then the cursor is also moved leftward. If text has been selected then the cursor is moved to just above the first selected character, and the selection is cleared.

The Down key moves the cursor to the same position on the next line. If that line is too short then the cursor is also moved leftward. If text has been selected then the cursor is moved to just below the last selected character, and the selection is cleared.

5.7.6   Traditional Key Combinations within an Input Area

The B2G User Interface supports input area navigation via dot key chords that are commonly used by other products (screen readers, note takers, etc).

5.7.7   Password Fields

If the input area is a password field (one in which the characters being typed don't appear) then the B2G User Interface automatically switches to Computer Braille (see Typing in Computer Braille). This is done because it's extremely difficult to accurately enter a password in Literary Braille, especially when it contains special characters and/or when a braille code that defines contractions is being used.

The message (see Messages):

password field

is displayed whenever you move onto a password field in order to alert you that you won't be able to read what you're typing and that you need to be typing in computer braille.

Android has an accessibility setting named Speak Passwords that affects how what you type within a password field is rendered. If it's disabled (the default) then each character within a password field is rendered as an asterisk [*]. If it's enabled then password fields are rendered in plain text. While enabling this setting makes it easy to be sure that a password has been typed correctly, be aware that, in addition to being on the braille display (which can be read privately), if speech is enabled then it's also spoken (which can be overheard by others).

5.7.8   Spelling Correction

You can browse the input area for misspelled words either by pressing Space+Dot8+z (dots 1356) to look for the next one or by pressing Space+Dot7+z (dots 1356) to look for the previous one. When on a misspelled word, you can get a list of suggested spellings within a pop-up (see Pop-ups) by pressing Space+Dots78+z (dots 1356). Either navigate to the correct suggestion and press Center to fix the word or press Enter to cancel the operation.

5.7.9   Protecting an Input Area

You can protect an input area against inadvertent modification (accidentally typing, etc) by disabling input area editing. This is done by pressing Space+Dot7+e (dots 15). Pressing Space+Dot8+e (dots 15) reenables it. When disabled, any action that would normally modify an input area results in a message (see Messages) that input editing has been disabled.

5.10.1   The Directional Keys When on a Slider

A slider is normally adjusted by tapping the desired point along it's bar. This, of course, can't be done on a device that doesn't have a touch screen. Instead, use the Left and Right directional keys (on the D-Pad) to adjust it.

• The Left key decreases its position.
• The Right key increases its position.
• The Up and Down keys don't do anything.

5.11.1   Following a Reference

Since the find prompt is an input area, the current clipboard content can be pasted into it. This capability makes it fairly easy to follow a reference (see, see also, etc).

The first step is to copy the reference to the clipboard:

1. Move to where the start of the reference is visible.
2. Hold Backward while pressing the cursor routing key behind its first character.
3. Move to where the end of the reference is visible.
4. Hold Forward while pressing the cursor routing key behind its last character.

The second step is to search through the text for a match:

5. Press Space+f (dots 124) to bring up the find prompt.
6. Press Space+Dot8+v (dots 1236) to paste the reference into the response.
7. Press Enter (dot 8) to search forward for the reference.

The next match may, of course, be another reference rather than the referenced header. You may, therefore, need to continue searching further forward with Space+Dot8+f (dots 124), or to search backward with Space+Dot7+f (dots 124).

6.1.1   Adding and Removing Shortcuts

Regardless of which launcher is being used, the B2G User Interface supports the following home screen management operations:

• To add a shortcut to the home screen:
  1. Go to a list of all the apps currently installed on the B2G. The easiest way to do this is to press Space+g (dots 1245). To do it via The Standard Android Launcher:
     1. Go to the home screen.
     2. Open the Apps drawer (on the favourites bar).
  2. Navigate to the app that you'd like to add.
  3. Press Space+Dot8+home (dots 123456).
• To remove a shortcut from the home screen:
  1. Go to the home screen.
  2. Navigate to the shortcut that you'd like to remove.
  3. Press Space+Dot7+home (dots 123456).

If you'd rather not search for the app then find an empty line within any input area (see Input Areas) and type it. You only need to type enough characters to uniquely identify it among all of the apps that are currently installed on the B2G. Letters can be in either lower or upper case, and they don't need to be at the beginning or end of the name.

When you're finished typing, press the key combination for the shortcut action that you'd like to perform (see above). If the characters match more than one app then the list will be presented within a pop-up (see Pop-ups). If this happens then navigate to the one you'd like to add or remove, and press Center.

6.1.2   The Standard Android Launcher

The standard Android launcher allows you to switch between five home screens. Each of them has a search area at the left, a favourites bar at the right, and a large, customizable area in the middle.

The default home screen is the middle one [Home Screen 3]. Pressing Android's home key (either Space + Dots123456 or pressing Down while holding Dot4) when on any other home screen goes to this one. In other words, pressing Android's home key twice guarantees that you're on the default home screen.

The search area (at the left), as it's rendered in braille, has a Search icon at the very top and a Voice Search icon at the very bottom. On an actual screen, there's an input area at the top that contains the text being searched for, and the space between it and the Voice Search icon (at the bottom) is where the search results appear.

The favourites bar (at the right) is a vertically-oriented set of shortcuts and/or folders. It also contains the Apps drawer which, when clicked, brings up an alphabetically sorted list of all of the apps that are currently installed on the device. Up to two shortcuts and/or folders may be above the Apps drawer, and up to two may be below it. The favourites bar should contain your most frequently used apps because, although it's customizable, it's the same on all of the home screens.

The customizable area (in the middle) occupies most of each home screen. A new shortcut is added to the customizable area of the home screen nearest to the default one that isn't full. When there's a choice, preference is given to the home screen with the higher number.

In addition to Adding and Removing Shortcuts, you can also reorganize this area by dragging the shortcuts within it to new locations. See Dragging Screen Elements for instructions on how to do this via the B2G User Interface.

A shortcut can also be dragged to, from, or along the favourites bar.

6.1.3   Initial B2G Home Screen Content

The favourites bar, from top to bottom, initially contains:

1. The Chrome web browser.
2. The NBP editor.
3. The Apps drawer.
4. The Google People (Contacts) app.
5. The Google Calendar app.

The customizable area of Home Screen 3 initially contains:

• A clock (in the middle, at the top).
• ES File Explorer (toward the left, at the bottom).
• The Android Settings app (toward the right, at the bottom).

The customizable area of the other home screens is initially empty.
