title: I have multiple windows in Emacs, (C-x o) will take me to the "other" window, what does other mean?
body: <p>I'm new to Emacs. I'm confused about the <kbd>C-x o</kbd> command. This command will move the focus to the <code>other</code> window. If I have many windows, which window will be selected as the target? What's the quickest way to do this?</p>
  
  <p>Thanks</p>
