Create Menus for GUIDE UIs
3 Fill in the Label and Tag fields for the menu. For example, set Label to File and
set Tag to file_menu. Click outside the field for the change to take effect.
Label is a string that specifies the text label for the menu item. To display the &
character in a label, use two & characters in the string. The words remove, default,
and factory (case sensitive) are reserved. To use one of these as labels, prepend a
backslash (\) to the string. For example, \remove yields remove.
Tag is a string that is an identifier for the menu object. It is used in the code to
identify the menu item and must be unique in your UI code file.
