Use the untearoff command to remove a button from the tear-off region of the main Prism window. Put the button's label in quotation marks. Case and blank spaces don't matter, and you can omit the three dots that indicate that choosing the button displays a dialog box. If the tear-off region includes more than one button with the same label, include the name of the selection's menu in parentheses after the label.
Changes you make to the tear-off region are saved when you leave Prism.
This command is not available in commands-only Prism.
