Safari: Shortcut to switch between developer window and safari In every other application (including Chrome I'm coming from - before the Catalina update) I was able to switch between windows with Cmd + ` (on a German keyboard that is Cmd + >).

Is there a shortcut to switch between an undocked developer window and the safari browser window?

I'm not talking about switching Tabs (I fixed that already :D).

Update
I just saw, that I can change FROM browser TO dev window with Cmd.+ ` but not back. (!!? :D)
Switch one way: Cmd + `

Switch the other way: Cmd + Shift + `


Replace ` with the necessary language specific equivalent.
Your solution was very close. Normally the key combination you mentioned loops through available windows. In this specific case you have to return to a previous window by adding Shift.
