This opens up the Open dialog. Take a close look. You will be using it many times. When you click the arrowhead, a list of options drop down. Click on the option you want to choose it.
Dialogs are windows, so they have title bars.
When you start Works, the first thing you see is the Startup dialog. With the right drive, the right directory and the right file selected, click on the OK button. The elevator box shows your location within the file. Click on the arrowheads for small movements. Click on the bar near the arrowhead to move one full screen at a time.
