Cursed Windows fact: you can activate keyboard shortcuts even if you press the keys on different keyboards
More cursed: this triggers the release of the first key separately, so Win+R opens the run dialog when pressing R, and then the start menu when releasing the Windows key.
(In the video, I only test this with the start key on the laptop keyboard, but that’s just because I can’t show the other way while holding a camera. The behavior is the same, I promise.)
