Text Box and Combo Box

Question

I have a form that contains two text boxes, one for first name, and one for last name. I also have a combo box filled with names from an Access Databse that is hidden behind the last name text box. When the user types in the last name box, the combo box will drop down with possible matches to the complete name. However, the mouse disappears so it is diffcut to select a name from this drop down of names. I would like to have a sort of "auto complete" feature so that you dont have to type the name in, you can simply select it from the drop down. But I dont know how to code the selection. is it possible to do this at all? Any help is appeciated thanks!
