I'm trying to write a GEM application, and I'd like to use keyboard equivalents for menu item selection. How is this done? I see keyboard equivalents mentioned in the docs, but how do I add them to the resource file? And how does the application know that a keypress is a menu equivalent? Is there some AES function that will tell you if a keypress is a menu shortcut? Any help would be appreciated... ---jb (jfbruno@rodan.acs.syr.edu)

Unless I'm doing it all wrong, you call evnt_multi() and look at the
returned value to determine whether you've received a menu message,
a keystroke, or whatever. Then you either evaluate the contents of
the message buffer or look at the keystroke values, as appropriate.
(This is why GEM programs wind up with such hellishly long sequences of
nested switch-case statements.)
All the resource file does is describe objects to be drawn. The convention
for indicating that there is an ALT key alias for a menu function is that
little doohickey that looks like a reverse-video gunsight, but I don't
recall what control-keystroke produces it.
