The limited functionality is a complete time drain. My guess is that these questions are vetted on a standard version of Excel where F2 and F4 work properly so they might not realize how much longer it takes without those keys. It also doesn’t help when you can’t copy formulas from formula window to formula window. Or when you drag a link with a formula, the F4 undoes itself. I made this comment in the survey. I imagine most (if not all) of us who use “real” Excel on a daily basis struggled with the clunky spreadsheet environment.
