[BRLTTY] Alert Tunes, smarter braille sense key bindings

[Rob]

The entry in the manual for this feature is rather sketchy, so I have some questions.
1. Where exactly do you set up the alerts to sound?
2. I have two sound cards. Where do I set the PCM device to use? I want to have the tunes come out of card 1.
Now, onto the Braille Sense bindings.
You cycle through the menu options with the backward and forward scroll buttons. But some of the menu entries do not fit entirely on the display; and you use those buttons to pan through the rest of the item. However, while in the menus, you cannot do this because it cycles the options. I suggest the choices in the menus be cycled with the space bar.
