Not really but where do you press these? Say I have the editor full screen. Do I switch to a different tab/split/window? In Zellij I press <meta+f>+<enter>. Pressing <meta+f> again will hide the floating window and I'm right back in the editor. I don't use this all the time, sometimes I have a terminal open in a split, but it can be pretty convenient.
I use iTerm in visor mode, so ctrl-~ (tilde) shows my terminal tabs and changes focus to them. Pushing it again hides them and returns focus to the previous app.
