Shift + ? = accent capital E?! [closed]
I’m not sure how I do it, but from time to time pressing Shift + ? doesn’t give me ? but an accented capital E. My wife showed me how to turn it off with Shift + Ctrl + Shift (i.e., press all three keys at once [yes, both Shift keys]), but I’d like to know how I manage to turn this on in the first place. Any clues?
