Menu System Problems

• You want to allow the user to select a menu item by pressing more than the one character of the menu field.

  This is not possible in this release.

• You want to prevent the Quit key (KEY_ESC) from quitting the current menu and returning to the previous menu.
  
  The only way to do this is to remove the event function km_esc() from the menu event table. You can remove this function from the event table by calling:

et_rplevnt(KEY_ESC, (EVENTPTR) NULLFP, MNETP);

The Escape key can be disabled from quitting the top-level menu by setting the MNTOPESCAPE form option off. See Chapter 22, "Using Menu Options and Features," for more information.

If you disable the Escape key, you must provide a menu selection that allows the user to quit from the menu. Otherwise, the user will never be able to leave the menu.
