Yeah.
You see, this is done with coding. But Access makes this easy for newbies by doing all the coding for you.
After the button is added, if you use the wizard as suggested, look at the Event tab of the properties window for your new combo box. You may notice that the On Click event has an Event Procedure in its field. You may look at the code that Access wrote for you by clicking the button with the three dots (...) in the On Click field.
You will come back to this a lot in the future, as you get more comfortable with code (or maybe not). Access does a good job at simple things like opening forms. But for added flexibility and options in the future, homemade code can be very useful. For fun, you may try messing with the code on a temp db.
