[BRLTTY] Which BrlTTY commands are the equivalent of a Tab and Shift+Tab in a GUI?

[Willie Walker]

Hi Hermann:

We definitely have room for improvement when it comes to allowing the 
user to interact with an application from the braille display alone.  We 
have opened http://bugzilla.gnome.org/show_bug.cgi?id=521599 as a means 
to compile the ideas.  If you have some, please add them as a comment to 
the bug.

The two main things we will need are:

1) The physical action taken on the display and/or what BrlTTY command 
is entered on the display.

2) What Orca action should be taken in response.  This is typically done 
via an input event handler that already exists in Orca or which should 
be created.

For example, the approach I was thinking about taking with the specific 
thing that started this thread was to define an input event handler to 
synthesize a keyboard combination.  Then, I'd bind the to-be-determined 
BrlTTY sequences to call the input handler so it could synthesize a Tab 
or Shift+Tab.
