I'm curious what your use of PrtSc is that is that important to you. I don't think I've pressed that key since the 1990s. Am I missing out?

On Linux I have it bound to flameshot, which you can consider the equivalent of Snipping Tool on Windows or Cmd-Shift-4 on OS X.

It's a key that's very useful on Windows for screenshotting.

Personally, I use it for various color inversion profiles (ex OLED: make all the dark greys pitch black, night time: black and red) + for ShareX.
