Log:
  Typebuf feature for ilist: type in several chars and an item with
  a matching label would be selected. Kinda like EFM's typebuf. Does 
  not show what you type, since I think it's useless here. If you hit
  Esc or wait 3 seconds, the buffer would be cleared. Understands 
  wildcards and is case-insensitive. Useful to dig through applications
  or bindings list. If you feel like this does not fit here, go ahead 
  and revert.
