how to learn vim

Here’s how you learn a new editor:

• Start with a tutorial (i.e. this lecture, plus resources that we point out)
  
• Stick with using the editor for all your text editing needs (even if it slows you down initially)
  
• Look things up as you go: if it seems like there should be a better way to do something, there probably is

vim modes

from normal mode: - i to enter insert mode at the cursor - o to enter insert mode on the next line
