Hi!
I have the same issue. Shortcut ALT + S normally makes a polish letter "ś" and now i - after the upgrade to 10.2.4 build 1949 - it starts to make a screen shot.
And there is now no way to edit the shortcuts. So, as a consequence, use of my beloved Evernote is annoying and much less ergonomic.
Please let me know, if there is a way to edit the shortcuts? Or is it shortly planned to be?
Best regards for the team.
