Win + shift + S brings up the new version of the snipping tool, win + shift + arrow key moves your window (left and right to change displays, up to fit the window vertically, down to minimize).
Ctrl T most know for opening a new tab. Ctrl shift T a lot don't know, opens previous tabs. Aka all those times you closed a tab and then realized you needed it 10 mins later... You can reopen those. (Also if you close edge/chrome and lost your tabs somehow, when launching fresh often Ctrl shift T will relaunch all of them on one press if needed). Work environments usually push Edge and chrome use a lot.
Also many don't use Windows V. Instead of Ctrl V which pastes the last item copied, windows V opens the clip board so you can paste one of the last few things you copied. Aka all those times you paste and didn't realize you copied a link or something after and now lost what you were trying to paste, you can turn it on using win v and it will stay on for future use.
