In Vim is there more than one way to leave insert mode?

Question

There are several commands that do something and then enter insert mode. Are there also commands that leave insert mode and do things?

For example, I frequently do this.

Answer 1

Pressing Ctrl-L leaves insert mode in evim, so why not in regular vim, too? Add this to your vimrc: :imap

Or if you don't want to configure vim use Ctrl-[, as suggested by others.
