In OF2 for Mac, is there a mechanism to prevent loss of an entry when escape is pressed? In OF1 I recall there was an option to adjust the behaviour, but don’t see anything in preferences…
Whenever I use the quick entry screen, I always use Command-S to save the quick entries I typed in. I never use the escape key.
If you go to OmniFocus preferences under Outlining and choose Classic Mode rather than Modern Mode, escape will confirm your entries. Give that option a try. It does impact everything in OmniFocus and not just Quick Entry however.
Hope this helps!
