Thanks for trying but it doesn't answer my question.
I was trying to keep my question short, so here is the long explanation.
I used to have a keyboard with CUT, COPY & PASTE as single keystrokes. Now I
have a new keyboard without them, and I miss them. I want to make 3 adjoining
keyes (say F10, F11, F12) into SINGLE STROKE SHORTCUTS. I have achieved it
with Corel & Word but can't do it with Exel.
