I've created lists for dropdown menus for validation in certain cells for
users to pick from the list. I want the user to be able to tab into that
cell, hit the down arrow on the keyboard to drop the menu, AND/OR then hit
the first letter of the selection they want on the keyboard, and hit enter to
make their selection.

It would be even nicer if they didn't need to drop the menu down but instead
hit the first letter (or even few letters) to find the selection they
want...you see this on websites a lot and I'm hoping Excel has a way to do
it. Hope that makes sense.

Is that possible? If so, how?

Thanks in advance for your help!
