Is there a shortcut in Samsung DeX to minimize all windows and display the desktop?
win (meta) + up = maximize wim + down = minimize wim + m = maps win + s = SMS win + d = desktop/minimize all win + f = finder/search device win + k = calendar (kalendar??) win + L = lock win + enter = seems to also be show desktop win + q = quick settings panel (wifi/bt etc on/off controls) win + e = email win + I = bixby, unavailable in DeX mode win + P = music default app win + left/win + right = pin app to 1/2 of screen side by side
"Meta+Enter" will minimize all the current open windows on the desktop and pressing "Meta+Enter" again will reopen the windows.
You can also press "Meta+/" to view all the default shortcuts on Samsung DeX.
If you want more than the default shortcuts then you can install an app called "Desktop Hub". This app will give you lots of extra cool shortcut keys for different stuff on Samsung DeX.
