item. An item is selected by rotating the wheel (or using the cursor keys) to place the
blinking cursor on the item, and then pressing the wheel (or ENTER key). When an item
is selected, the text of that selection is returned.
• Pressing the EXIT key will not abort the script while the menu is displayed, but it will
return nil. The script can be aborted by calling the exit function when nil is returned.
