ListBox Property where 'focus' triggers selection
 

Many of my applications have ListBoxes where the user makes a mouse-
click to record their selection. Is there a property within the
ListBox control that sets the 'focus' to record the selection, in
addition to a mouse-click?

For instance, the user does not have to scroll through the entire list
of selections in the ListBox, they can simply type the first letter of
the name they are seeking. But then they have to click on a different
name and then click back on the name they wanted in the first place in
order to record their selection.

Thank you,
