Look, I right-clicked $1.2 million.

Ctrl + Shift + S on Windows, Cmd + Shift + 5 macOS (it might be option instead of shift actually).

For me it’s win+shift+s on windows, not ctrl. At least if you’re taking about being able to select part of your screen to screenshot, without having to crop after the fact.

Also alt+printscreen to screenshot just the selected window.
