title: In Vim is there more than one way to leave insert mode?
body: <p>There are several commands that do something and then enter insert mode. Are there also commands that leave insert mode and do things?</p>
  
  <p>For example, I frequently do this...</p>
  
  <p><kbd>control</kbd><kbd>[</kbd> <kbd>:</kbd> <kbd>w</kbd> <kbd>return</kbd></p>
  
  <p>Before I create a mapping, is there already Vim command that does that?</p>
