...I also thought of scroll lock and number lock and couldn't find anything. It definitely seemed
that way. You are correct on the F14 key. On my spreadsheet, at the bottom, there are indicators
for CAPS, SCRL, NUM. Although the numbers are apart from the up/down/across arrow on my
keyboard (see below), it was still the Numbers Lock and the F14 key worked just fine.

A huge THANK YOU, Bob.
