On my Linux setup, specially with vim/neovim, I have:

• CapsLock and L Control keys swapped;
• If CapsLock (physical key location) is pressed for less than ~300ms, then it is not mapped to L Control, but to Escape instead.

Or, in other words:

• L Ctrl maps to CapsLock
• CapsLock maps to:
  • L Ctrl if pressed for longer than 300ms;
  • Escape otherwise.

This allows me to quickly enter normal mode (nvim), cancel things, etc., with little movement from my left hand (and since a lot of keyboard shortcuts use Ctrl key, it is very useful to have Escape in the same place). Having this on Windows as well would be an awesome Windows experience.
