I'm now in the habit of typing the opening backtick, ctrl+shift+v to paste some line of code, then having to WAIT a second or 2 and then type the second backtick. That usually formats it correctly. But I'm also very quick on the backspace and retyping the closing backtick, which is sometimes necessary.
Starting a new chat with someone in your organisation that you haven't chatted to is also annoyingly slow. This one I keep forgetting. So I search their name in the search bar, choose the hit from the dropdown and immediately start typing, only to notice that my initials 10 keystrokes didn't register, because the new chat was still initialising.
I'm curious, do you touch type? I'm also at about 100wpm, but only thanks to learning to touch type.
