Computers Shortcuts that Noone knows

Can anyone text any shortcuts for using computers that anyone rarely knows ?
A couple of Shorcuts from Me:

Right Click+w+t = A new text document
F2 = Rename a folder/file
ctrl+shift+w = Close a chrome browser
ctrl+shift+esc = Control Panel

windows key and tab = preview with tabbing
windows key + shift + s = snapshot

WIN + L = Lock
This is useful if you want to quickly lock your pc
Also win + x opens a menu to open cmd and shutdown etc

Win + Tab = New window and open task manager to exit a game that is not responsive on the original desktop screen

learnt this in a repair shop,
Ctrl+shift+f3
when ur on the windows 10 setup phase ( like when they ask you to sign in and create a password )
that will automatically log u into administrator, good if your client wants some software installed but they dont want u to sign into any of their stuff.
