Send a keystroke to Xy?

[Harry Binswanger hb@xxxxxxxx]

Hi. Due to the vagaries of Tame, which loses its settings only calls to
DOS, I need to have an XPL routine that will send a keystroke that can be
intercepted by Autohotkey.
That is, I now have an Autohotkey macro that moves the mouse to click on
the icon at the top of Xy's window, which invokes the Tame Console, and
then the macro sends "dl" which reloads the Tame settings from its
configuration file. That restores the display to the right state. But how
can I invoke the AHK macro without me having to enter a keystroke manually
to do so? I have tried compiling the AHK macro to an .exe file, but
whatever version of DO and DOS I use, it either doesn't activate the AHK
macro or doesn't produce reliable results.
So what I'd like is for an XPL routine--without any shelling to DOS--to
"send itself a keystroke" which AHK can then intercept, just as it does
when I type the "hotkey" on my keyboard.
I'm using alt-ENTER as the hotkey, so if an XPL program could make AHK
think alt-Enter has been typed, all would be hunky-dory.
I suppose this would be done by some kind of function call or equivalent
thereof, since function calls do things like move the cursor on the screen.
Just printing a keystroke to the screen is not an event AHK can notice.

Thanks for any ideas.
