title: Vim auto complete
body: <p>So I know you can get Vim autocompletion with <kbd>Ctrl</kbd>-<kbd>X</kbd>, <kbd>Ctrl</kbd>-<kbd>O</kbd> but I'm wondering if you could rework it so it works with just pressing <kbd>Tab</kbd> (more like Textmate's snippets), or even just how I could remap it to something a bit shorter (even if I can't get fancy tab completion), as I find <kbd>Ctrl</kbd>-<kbd>X</kbd>, <kbd>Ctrl</kbd>-<kbd>O</kbd> a bit awkward.</p>
