Pop-up Menu
A pop-up menu is associated with a widget. The pop-up menu can contain one or more items as well as nested submenus. Figure 22–2 shows two button widgets. When you choose the button Hi, a pop-up menu that contains five choosable menu items appears.

In a graphical interface, you can press and hold the mouse MENU button to pop up a menu by default or use SHIFT–F10. To choose an item, move the mouse pointer to the item and click the SELECT button. You can define a different mouse button to use by setting the MENU–MOUSE attribute of the menu.
In a character interface, use the key associated with the DEFAULT–POP–UP key function (usually ESC–U; F4 on Windows). Use the up and down arrow keys to move within the menu, and press RETURN to choose a menu item. You can use this keyboard method in both character and graphical interfaces.
