pbl0m, German Ohh I missed that so hard 😆
I switched to #kde_plasma couple month ago on my private laptop and as a longtime #gnome user I love to use the [superkey] to overview all windows. Finally I got this to work in KDE😍
Just use the following 2 commands.
~$: kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta "org.kde.kglobalaccel,/component/kwin,org.kde.kglobalaccel.Component,invokeShortcut,Overview"
~$: qdbus org.kde.KWin /KWin reconfigure
