>>Is there a way to programmatically clear or change the value in LASTKEY? I'm trying to do this using KEYBOARD, but I'm on a ReadOnly grid and every parameter I enter (KEYBOARD etc.) causes a beep and readonly message. CLEAR TYPEAHEAD clears the buffer , but not the LASTKEY value...any ideas?

Excellent idea. I just had to set KeyPreview = .T. and it works fine. Thanks Edward.
