I'd forgotten about type, thank you!

But sadly 'type' doesn't do what I need; it simulates typing for the Rev 
stack, but not for the system.  Evidently a browser instance is really a 
window layered on top of the stack (at least on Mac); 'type' has no effect if 
the focus is on a text field in the browser instance.   I don't think 'type' 
does anything you couldn't do in transcript, finding the selection in a field 
and inserting characters.

So, thank you for the suggestion; but I'm still looking.  Granted that 'type' 
exists, I'm more doubtful if there is anything else in Rev (though I'd still 
be delighted to be 'reminded' of something else that I'd 'forgotten'); does 
anybody know of ways to fake a keypress to the system?  Evidently it's 
possible at a Cocoa or similar level, as there are various programs that for 
example allow you to use an apple remote and selectively map buttons on the 
remote to keypresses.  But I don't even know how to do it at that level, and I 
was hoping to avoid writing my first external for about five years...

TIA,
