Created attachment 123513 [details] Plasma settings touchpad dialog SUMMARY STEPS TO REPRODUCE 1. Open settings manager 2. go to touchpad 3. use Alt+C to trigger the Tap-to-click checkbox OBSERVED RESULT Pressing Alt+C triggers the Cancel button, not the Tap-to-click checkbox, closing the Touchpad dialog. By default tap-to-click is disabled on Plasma desktop, so users without a physical mouse cannot enable touchpad tapping via keyboard. EXPECTED RESULT Pressing Alt+C should have triggered the Tap-to-click checkbox SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Arch Linux, Kernel 5.3.7 (available in About System) KDE Plasma Version: 5.17.1 KDE Frameworks Version: 5.63.0 Qt Version: 5.13.1 ADDITIONAL INFORMATION I never had this problem with Kubuntu 17.10/18.04 (I forgot what version of Plasma that was); Alt+C was only assigned to Tap-to-click and not the Cancel button.
Needs the accelerator set to some other letter I guess.
Nowadays the KCM always opens in System Settings rather than KCMShell, and in System Settings, the Cancel button isn't shown. This means the bug has effectively been fixed for everyone except people who manually run `kcmshell{5,6} kcm_touchpad`. Fixing it there is not worth the effort given how niche of a use case this is; marking as (effectively) fixed.
