Keyboard Access For gdb-ui.el (from emacs 21.3.50 CVS)

[Nick Roberts]

Hello Raman,

I've cc'ed this to emacs-devel as its a wider (and more pertinent) group
than emacs-pretesters, I think. I hope thats OK.

The current version of gdb-ui.el (CVS version 1.39) has two commands for
selecting an array slice bound as follows:

(define-key map [mouse-2] 'gdb-mouse-array-slice)
(define-key map "\r" 'gdb-array-slice)

Does the second binding do what you want?

In general I have tried to make the mode work on graphical displays and
text-only terminals and I think most other developers do the same. 

Robert Chassell has given me advice for emacspeak in the context of
documentation. To be honest though, I don't understand how gdb-ui.el can work
with emacspeak. For example, breakpoint locations are shown by an icon or
character in the display margin. How does this work with emacspeak?

In general, if you explain exactly how a feature should work, then I will be
happy to try to implement it.
