auto searching technique

[Devin Asay]

I know this has been discussed before, but I'm not having any luck in  
the archives, and I can't reach Rev Online for some reason. :-(

Has anyone developed a handler for doing an active search for a line  
in a combo box popup while typing in the combo box? So if my combo  
box contains a list like this, in alphabetical order:

Apple
Banana
Cantelope
Grape
Kiwi
Orange
Peach
Pear
Pineapple
Plum
Raspberry
Strawberry
Watermelon

And I start typing "p", the list pops up with the first item  
beginning with "p" hilited. Or more accurately, the first item  
beginning with 'p' with everything after 'p' hilited. Then as I  
continue to type "pi", Pineapple is (partially) highlighted. Sort of  
like auto-complete in a web browser url field or my Mail program's  
address field.

I know this can be done, but it's eluding me at the moment.
