[ESS] jumping to a function's definition

The interface that I'd be interested in seeing would be an "iswitchb"
approach to jumping to functions in source code.  That would make
sense to me.

Thomas Gerds had a nice iswitch-r that completed R objects; I've got
on my to-do list a generalization of it (it's currently xemacs only).

I believe that ECB (Emacs Code Browser, the reason I added the imenu
stuff) might have a means of navigation via keymaps.  "Might".  It's
worth checking.

You should be able to use keystrokes to navigate the menu pull-downs,
but that is an ugly hack.
