That's actually a good habit to build.

Here's a windows utility you might find useful: https://github.com/susam/uncap

And here's an editor that's accommodating to your newly trained typing skills ;) https://www.vim.org/

I had to break this habit as well, and also as a result of the touchbar. I empathize with this struggle, it took me a couple of weeks to get used to capslock escape, but it was worth it.

GNU Readline has destroyed my ability to work on non-readline editors. It's worse when I am using a machine where caps lock means caps lock. I have it bound to control (on hold) and escape (on tap). When I typo on a different machine and reflexively type ^A^K to kill the line, it comes out as capital "AK" instead. Repeat multiple times.

Believe me, you'll love using Caps Lock instead of ESC very soon. I switched the two using Karabiner (for mac) and I wonder how I used computers all those years before that. If you use vim (or vimium on Firefox), you'll absolutely like this change.
