Hmm. Perhaps I shouldn't use pop-up menus at all... 

I have a related question, then: is there way to "pull down" a pop-up
menu from Lisp?

I need this for speech recognition corrections: if you click the right
mouse button on a word or on a region of text, a "corrections" menu
appears, showing the alternatives to what has been recognized. To choose
a correction, the user should be able to either:

  -- click a mouse button
  -- press a number key
  -- say "choose <number>"

Now, I guess the second option is out, so how would I implement the
third one? Is it possible to find out if a pop-up menu is currently
visible, and tell it to choose a particular menu item? Or, as a
workaround, just hide the menu?

If pop-up menus are not up to this, I might have to use a separate frame
with a special electric buffer, sort of like what ediff does. But I
really don't like this approach: it's not elegant, it's difficult to
use, and it's much more difficult to manage correctly.
