LV Is there a simple way to add the ability to reposition the listbox viewpoint based on a user's keyboard input? That is to say, if one has a scrolledlistbox containing, say, a hundred items, and the view of the list is 5 items, scrolling down 2/3 of the way in the listbox can take a while. It would be useful to have the ability to turn on a search config option that would watch for keyboard input inside the listbox and reposition the view based on the user's input.
