I just found this watching a youtube video on Mac OS tips.
I think it also works in Windows but my testing there was spotty as I currently run Windows in a VM and the Key translation from the Mac to the VM is a little strange.
Anyway.... You close a tab in Logos and... "Drat! I did't mean to do that!"...
No problem.... Shift-Cmd-T.... Shift-Ctrl-T in Windows "Should" reopen that just closed Tab for you. This works in other apps as well like browsers and such.
Don't know if this has been shared before but here ya go.....
