Question for Xt folks....

Suppose I have a Command button and asciitext widget in an app.  I'd
like to bind a RETURN in the text widget to a Button1 press in the
command widget.  In other words, if the user hits a RETURN in the text,
the command widget acts as if it had received a button click. (enter, down and
release)

It would be trivial to bind an action to the text widget to execute the
command button callback, but what I'm after is the highlighting in the
command button.  (this is what I'm doing now, I just don't have the
visual effects...)

Ideally, I'd like the text widget's "EnterNotify" event to get passed to
the command so that the command's "highlight()" action is called, then
the "<Key>Return" in the text widget does the command button's "set()
notify() unset()" actions.  (I'd also like the text's "LeaveNotify"
event to execute the command's "unhighlight()" action.....)

In short, I want to bind the visual effects of events in the command
widget executed from events in the text widget.

How do I do this?

Thanks
