Rebind the Meta Key¶
Using D-Bus it’s possible to query the set of available shortcut names
qdbus org.kde.kglobalaccel /component/kwin org.kde.kglobalaccel.Component.shortcutNames | sort
The kwriteconfig5 command can then be used to edit the kwinrc file to remap the key binding
kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta "org.kde.kglobalaccel,/component/kwin,org.kde.kglobalaccel.Component,invokeShortcut,<shortcut-name>"
Finally, poke KWin via D-Bus to reload the config
qdbus org.kde.KWin /KWin reconfigure
