NAME
       key_led_flag - Flag to prevent the keyboard LEDs from being updated. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       extern int key_led_flag;

DESCRIPTION
       By  default,  the  capslock, numlock, and scroll-lock keys toggle the keyboard LED indicators when they are pressed. If you are using these
       keys for input in your game (eg. capslock to fire) this may not be desirable, so you can  clear	this  flag  to	prevent  the  LED's  being
       updated.
