So far the only one i know is “alt tab”. i accidentally pressed something that displayed all the windows on the desktop, and that seemed like a neat trick. Anyone know more buttons and combinations to do to get KWin features?
Configure Desktop (Personal Settings)>Desktop>Desktop Effects>All Effects. Click into any of the effects and you can set what the hotkeys are or see what the current hotkeys are.
CTRL+F11 for Desktop Cube (if activated)
CTRL+F8 for Desktop Grid
CTRL+F10 for Present Windows (shows all the windows open)
Meta(windows button)+0 for Zoom to actual size
Meta+= for Zoom in
Meta± for Zoom out
