8.6.5.1 Choice Name Field

The choice name field specifies the text that menu displays for this choice. The choice name must be at least one character long, and it cannot overlap with another choice on the screen.

If you create a menu with a choice that does not appear in the same row or column as any other choice, the only way you can move the menu cursor to that choice is to type the first word of the choice. To prevent unreachable choices, the first word of each choice should be unique.

Since menu treats the ! and ? keys specially, you should avoid putting them in the first word of a choice name.
