I'm afraid, this was a missinformation or question. Alt+"," works. Even during Sort and the like.
I think there is a completly different problem with the desktop frontend. Sometimes after "Save" (to cloud) the whole environment seems to freeze in some sense. You can no longer see the editor insertion point (cursor) and Shift+Enter for Evaluation does not work. Very strange. I don't understand what's going on.
(I have Version 11.0.1.0 of Programming Lab and its desktop, Windows 10, 64bit. I did not notice this kind of problems with earlier versions.).
