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.
