Iconizing THINK Reference 
If your Macintosh has a small screen, you'll want to keep THINK Reference
out of the way until you need it. To shrink THINK Reference, click the
Iconize button in the middle of the Button Panel, or choose Iconize from the File menu. To bring THINK Reference back to full size, double-click on the tiny window.
You can also use the Iconize command in the File menu to iconize THINK Reference.
