OS X Vim control-6 buffer toggling fix


I recently obtained a new Retina MacBook Pro which will be my new development box, but was annoyed to remember that Terminal.app does not play well with the VIM feature, Control + 6 to toggle between two active buffers.

After talking in irc.freenode.com#vim and not getting answers, I Google'd harder and found this StackExchange discussion which explains clearly the issue is that non-standard escape sequences are necessary. The solution is to use Control + Shift + 6. This is annoying and unnecessary with the following fix I discovered after talking with my co-worker Dan Heberden.

Dan recommended I look into keyremap4macbook which turned out to be exactly what was necessary in order to remap. Unfortunately, it's not exactly self-explanatory how to configure custom key sequences.

KeyRemap4MacBook

Easy Fix

  1. Click Misc & Uninstall tab.
  2. Click open private.xml and from that Finder window, open in a text editor.
  3. Replace the contents of that file with something like:

    <?xml version="1.0"?>
    <root>
    <item>
       <name>VIM Fix</name>
       <appendix>Change Ctrl+6 to Ctrl+Shift+6</appendix>
       <identifier>vim.owns.whatever.fix</identifier>
       <autogen>
         --KeyToKey--
         KeyCode::KEY_6, ModifierFlag::CONTROL_L,
         KeyCode::KEY_6, ModifierFlag::CONTROL_L | ModifierFlag::SHIFT_L
       </autogen>
     </item>
    </root>
    
  4. Head to the Change Key and click ReloadXML.
  5. Click VIM Fix that now shows up in the remapping list.

So yeah, thats all there is to it. Hope this helps others out in the same boat.
