My biggest problem with Microsoft 365 is that it obstinately keeps using localized keyboard shortcuts, so if you're an non-English speaker, the usual English shortcuts like Ctrl+f don't fucking work.
I'm with you, drives me nuts that it is basically a guessing game on whether the shortcut for bolding the font is either Ctrl-B or Ctrl-G (gras, bold in French) and it varies by software, region, time of the day....
