But why? Win-Space is the default hotkey to switch keyboard language on Debian and Ubuntu, and Win-Tab will switch between activities on KDE/Plasma. It's very convenient!
Really? I just bought a new keyboard mostly because the Windows key broke on my last one. Win + arrow keys for window snapping is a huge productivity booster for me, but not having Win + V clipboard history was driving me nuts, and needing to manually snip my screen instead of Win + Shift + S was a pain.
Do you just use your computer for gaming and web browsing? Because I could see not using it outside of work.
Win + prnt scrn takes a screenshot of everything and saves it to a screenshots folder in pictures. Then it's pretty easy to crop it in the built-in photos app when you double click it.
The sniping tool automatically saves it, too. I use it all the time for giving tech help to colleagues and clients since the sniping tool allows for quick annotation then easy copy/pasting to emails.
Many ways to do the same task. Regardless, the Win key is very useful!
