If I got it right and Accel is Ctrl, then it conflicts with the developer console

Leider funktionier es bei mir nicht, da die Tastenkombination Shift+Ctrl+K die Entwickleransicht öffnet. Gibt es noch andere Möglichkeiten Tabs per Tastenkombination zu klonen/dupplizierene?

"Accel" key? guessing it is the Ctrl key (Command for Mac). Tried a lot of key combinations but it does nothing as far as I can tell. Useless waste of time.

Doesn't work.
Alt-Shift-K doesn't.
Alt-Ctrl-K doesn't.
Alt-K doesn't.
Ctrl-Shift-K opens developer console.
Why "K" anyways?
May be Ctrl-"Y" should be selected?
Finally, there are plenty of Ctrl-Shift-letters that are free.
