title: How do I make vim-style key bindings work on tmux using set-window-option?
body: <p>I am aware that I can manually bind individual keys in my <code>.tmux.conf</code> file, but <a href="http://blog.sanctum.geek.nz/vi-mode-in-tmux/">according to this page</a> I should be able to get vim-like key bindings in tmux simply by adding the following to my <code>.tmux.conf</code>, saving me having to maintain a list of keybindings:</p>
  
  <p><code>set-window-option -g mode-keys vi</code></p>
  
  <p>But this doesn't really seem to work as expected. Sure enough, when I press <code>Ctrl+b [</code> I am able to navigate through my terminal history using vim keys <code>hjkl</code>, but when I press <code>Ctrl+b k</code> it doesn't take me to the above window, for that I still have to press <code>Ctrl+b Up</code>, same goes for down, left and right.</p>
  
  <p>Why doesn't this work? Do I really have to map these keys manually on top of vi mode to get <em>actual</em> vi mode?</p>
  
  <p>I'm using <code>tmux 1.6</code></p>
