## Steps to reproduce: Settings / Configure Keyboard Shortcuts / Up / Alternate / Custom / <Backspace> | The "Backspace" shortcut is ambiguous with the following shortcut. | Do you want to assign an empty shortcut to this action? | Shortcut 'Alt+Left' for action 'Back' [Yes] ## Expected result: Backspace triggers Up. Actual result: | The key sequence 'Backspace' is ambiguous. Use 'Configure Keyboard Shortcuts' from the 'Settings' menu to solve the ambiguity. No action will be triggered. Alas, I see no way to solve the ambiguity here: the Back action is associated with <Alt-Left> as a shortcut and <Back> as an alternate, no <Backspace> to remove. Also, upon running Dolphin, it now says: | There are two actions (Back, Up) that want to use the same shortcut (Backspace). This is most probably a bug. Please report it in bugs.kde.org I agree with it: this is a bug. P. S. FWIW, I feel strongly, that <Backspace> = Up should be a default, following the decades old custom, respected by most classic file managers and already featured in KDE by Krusader.
Still a problem with Dolphin 21.12.3 on Kubuntu 22.04 LTS. Given how much I use this keybinding in the Kubuntu 20.04 LTS I'm preparing to upgrade off of, I may repurpose an old "block Ctrl+Q in Firefox but nothing else" script I wrote so it `XGrabKey`s Backspace while a Dolphin window is active and then emits a synthetic Alt+Up. I can't afford to wait through a decade of robots asking me to re-confirm that the bug still exists, only to give up and let them auto-close, like the other dozen plus bugs I've filed.
