Thanks, didn't realize that at first.  However, this is not Textmate style completion:

  • Doesn't complete the word in place (like tab completion does), but shows a list of completions.
  • Completion include many items that aren't really completions (e.g. "tar" will show completions like "toward and start").
  • Requires a extra keystroke (e.g. return) to apply the completion.
