In vim, you can travel through time! Today I have done many changes to multiple files and I didn't want to press u tens of times to undo it. I thought there should be a better way. And there is. It was 6 PM and I wanted to go to 10 AM. That's 8 hours. And the command I need to run was: :earlier 8h. OH. MY. GOD. How simple was that? And guess what would I needed to run if I want to go back to 5 minutes before or maybe 4 days? :earlier 5m or :earlier 4d. And then use :later ... to go forward. Example: :later 45s to go 45 seconds forward. I am speechless.
