My arrow keys no longer navigate back into bash history, but pop up the Rhythmbox app! How did I get into this and how do I get out? Fedora 33.

Is there a special key on your arrows with fn key? Maybe the keyboard is not configured correctly.
Fixed it. Settings → Keyboard Shortcuts disabled all shortcuts and logged out/in. Reset all shortcuts to defaults with the reset button - still works OK. Hmm … How did I get into this in the first place?
