I'm trying to reassign the side buttons on my logitech superlight to keyboard input. However, the side buttons default to to back/forward.

The settings window for reassigning mouse input is in a 'forwarded' position, so clicking the 'back' button on the mouse results in the settings window moving back a menu level instead of reassigning the button.

The 'forward' mouse button can be reassigned, though, as there is nothing 'ahead' in the menu.

I've previously had luck reassigning the side buttons using input-remapper, but I'm on tumbleweed which doesn't have input-remapper in its repositories.

Is there a way around this UI quirk in KDE that will allow me to reassign the 'back' button on my mouse?

Or have any other tumbleweed users had luck reassigning both mouse side buttons on KDE?

One other approach I can think of is if it's possible to disable/supress the default forward/back behavior in KDE.
