Learning Emacs

Emacs and vi/vim are the two most popular text editors on Unix. I'm currently learning Emacs (yes, learning, there's a bit more to it than Notepad).

The coolest thing I've found so far is Emacs keyboard macros.

• Type keys
  
• End recording with C-x )
  
• Execute recording with C-x e
  

You can combine the execution with C-u to repeat the command a given number of times.
