How to set up your shell to use vi command editing mode in Terminal

Most shells that have a command line editing feature support Emacs key bindings. (a tiny subset)

Up     Ctrl+P
Down   Ctrl+N
Left   Ctrl+B
Right  Ctrl+F
Home   Ctrl+A
End    Ctrl+E
Delete Ctrl+D

Alternatively, you could set up your shell to use vi command editing mode, by adding
  set -o vi to your shell startup file (e.g., ~/.bashrc).  Then, for example, you can

• Use Esc k Enter to re-execute the previous command (same as !!).  The minus key - also works as a "move up" command.
• Use Esc k k k k k k k k k k k  kEnter or Esc 12 k Enter to re-execute the 12th previous command (same as !-12).
• Use Esc and a motion command (i.e., k, suitably repeated), and then edit the bash command line you find there.  Remember, you will still be in vi command mode, so you will need to use a vi editing command (e.g., I, A, C, R, or one of their lowercase counterparts) to actually add to the command from history.
  So, for example, Esc k i sudo Space Enter is equivalent to sudo !!.
• For advanced users: you can even copy (yank) text from one line and paste (put) it on another, so you can accomplish results comparable to !-2:- !$.  (Unfortunately, it does not seem to support named buffers.)
