No, this is not quite what I am asking for.  Capturing keyboard events
is fine, but I need the button to click visually, for feedback purposes.
 Just like what happens if you define the control key shortcut and press
that.

So the question is either, how can I get GtkButton to respond to a
non-modifier hotkey, or how can I programmatically get GtkButton to
visually depress and release?
