Cool KDE Plasma Tip: Quickly access task manager apps with [Meta] + [number]
@[email protected]’s task manager usually lives in the panel located by default at the bottom of your desktop (see attached image).
Quickly open or display apps shown in the task manager by holding down the [Meta] (aka “Windows”) key and hitting one of the number keys at the top of your keyboard.
Reach the first app on the left with [Meta] + [1], the second from the left with [Meta] + [2], etc.
Note: you might encounter a bug where in different activities or active window, these shortcuts are calling the apps from the default activity, instead of currently active one. Not sure if this has been reported yet.
