Screwing with a keyboard combo in Excel... like Shift-Space to highlight a row... is like an IDE deciding to swap the key-bindings for '{' and '['. You'd have entire accounting and marketing departments in rebellion.

Devs consistently underestimate how many power users of Excel there are, and often don't understand how they operate.

Maybe by most users, but not by most users who use it for many hours daily for professional tasks (i.e. not just as a kind of tabular list editor).

Basically everyone in a white collar job who is NOT a developer is using Excel. I'm a developer, even I have to use Excel at work.

"Most users" are not who choose business software.
