I've recently read that some people put
inoremap jk <Esc> on their vimrc to exit insert mode without having to move their hands away from the home row. But then how do you type the letters
jk? Is this just not possible at all if you do this?
I read on an answer to this question that vim by default waits one second to see if you're gonna press anything else, but this hasn't been the case when I try it.
