How can I copy portions of a Prism sheet name to another sheet?

Select all or some of a sheet name. To copy it to the clipboard, click the right mouse button and choose Copy from the shortcut menu. Now go to another sheet, position the insertion point in the sheet name, click the right mouse button and choose Paste. The trick is that you must use the shortcut menu, not the copy and paste toolbar buttons or the commands on the Edit menu.
