I can see that in the "File" menu there is written "Save and Close (Z)". Does the "Z" have anything to do with a possible keyword shortcut for this action? Thanks

The shortcut for Save & Close in the Event window is Ctrl+L.

Unfortunately that does not work for me, and it is not what I see in the menu (see screenshot).

May that be because I am using the option "Edit events and tasks in a tab instead of in a dialog window."? Anyway, shouldn't work in that case as well?

The Ctrl+L shortcut is shown here on W11 for TB 102 and 115. When 'edit... in a tab...' is checked, the menu shows (Z) instead of Ctrl+L, and neither one works. So this is probably a bug, and can be reported to Bugzilla.

Thank you for your feedback. I reported it. We can archive this question.
