[BRLTTY] key bindings

[Daniel Dalton]

Hi,

How do I add a keymap for the braille note? (I want to make it toggle
autospeak.)
- should I be looking at the file Drivers/BrailleNote/braille.h
Or something else?
- do I just have to define a constant with #define refering to the right
keycode? (and using the name autospeak or whatever it is defined as on
other displays)

Or is there something else I should do? How do I determine the key code?

Thanks!

Daniel.
