Some people prefer using
jk, but I prefer
jkfor two reasons:
jkis typed with two separate keys, so you can “roll” your fingers instead of using the same one twice, and pressing
jkin normal mode out of habit will move down and then up, leaving you exactly where you started, whereas hitting
jjin normal mode will move you to a different place in your file.
Compelling. I’m giving it a go. Lots of j’s showing up in my text right now though.
