If you're using bash or zsh and you don't know the ^X^E shortcut, learn it now.
First, ensure you have a valid `EDITOR` environment variable set to your favourite editor (like vim or emacs).
Second, enter some command, but don't hit enter.
Third, use Ctrl+X Ctrl+E and learn that you can use your editor to modify the command before running it in the shell.
This is pretty helpful if you're trying to edit a long command line.
@antekone Also note that, if the $EDITOR exits with a non-zero exit status, the shell won't run the command. In vim, that's `:cq`. In ed(`) (without GNU's "--loose-exit-status" parameter), any editing error will produce a non-zero exit status, meaning the command won't run. Edit with care. For all editors, if you want to abort, you can delete the entire command, save, and quit.

@antekone sigh. "ed(1)", not "ed(`)"
Keyboard proximity colluded with my failure to watch the screen as I typed.
