Lab: the absolute minimum you need to know to edit a file in vi/vim

1. leaving vi(m) properly (killing processes not allowed)
  a) start vi or vim, then get out of vi(m) as fast as you possibly can!
  b) start vi or vim, go to insert mode, make a change,
         then get out of vi(m) as fast as you possibly can!
  c) brag to someone that you know everything you need to know about vim

2. locking the terminal
  a) start vi(m), lock the terminal, exit vi(m)
  b) use "stty -ixon" and verify that you no longer are able to lock the terminal
  c) optional: add this line to your ~/.bashrc to disable locking permanently

3. saving changes
  a) start vi(m) with a file
  b) insert all of the vi(m) commands you can remember
  d) go back to normal mode
  c) save the file
  e) play around with hjkl until you can comfortable navigate with these keys
