I once found that my old Microsoft Ergonomic Keyboard had an option to disable the Caps Lock Key in the settings. I immediately used that. Then after a reboot Caps Lock was ON and the Key was disabled - Shift now also didn't disable Caps Lock...

That taught me that sometimes you need the Caps lock Key badly...

Software can control the state of the key - and you need a way to get rid of that. Back in the day - to enforce only Upper-Case Text in some Text-Field - some software even messed with global Casp Lock State when entering the Text-Field...

> there people that use the caps lock key?

Yes, of course. Because I programmed my Keychron for it to be a regular LShift. Works very good for my hands. But when I'm on the regular keyboard I have a real trouble with typing or entering passwords, but it's manageable.

> Cant remember using a function key

I use it for the volume control when I'm in a fullscreen app or with both hands on the keyboard - but only because my Fn is on the right and volume controls on F10-F12.

The caps lock key is good for binding to F13 and using for push-to-talk. I know some people bind it to escape for Vim usage but I don't like that because I'm likely to also use Vim on machines without that key remapped and that messes with muscle memory.

> are there people that use the caps lock key?

I for one do. Old habit when typing in longish C constants (ECONNRESET) or shell environment variables. I'm used to typing capitals by holding the Shift with the pinky of the other hand than the one entering the letter, so with long strings of capitals sometimes I'd have to switch for every other letter, which gets old fast. With Caps Lock, I press it, type in the letters, press it again.

Completion mostly works these days if you have it, but you don't always.
