Disable the Super key in KDE Plasma.

What#

KDE Plasma has a similar behavior to Microsoft Windows concerning key bindings. Left Meta(Win) Key will the trigger application launcher. And it’s not straightforward to remove this behavior.

Why#

I just configured kwin-bismuth with similar bindings to sway window manager. And I used a lot of Meta modifiers. It’s quite annoying to accidentally trigger the application launcher.

How#

# config ~/.config/kwinrc
kwriteconfig5 --file kwinrc --group ModifierOnlyShortcuts --key Meta ""
# reload kwin
qdbus org.kde.KWin /KWin reconfigure
