StickyKeys help users who have difficulty pressing more than one key at a time. The Windows' implementation of StickyKeys only makes the Shift, Control, Alt, and Windows keys sticky. However, System Access also uses Caps-Lock, Insert, Scroll-Lock, and NumPad 0 as modifiers. When you press and immediately release a modifier key while using StickyKeys, the system plays two short tones. The system cancels the modifier when the user types a non-modifier key, such as a letter, or clicks the mouse. Alternatively, if the user presses and releases the same modifier key twice in succession, the system locks the modifier and plays one short, higher-pitched tone. When the same key is press for a third time, the system then unlocks the modifier and plays one short, lower- pitched tone. If you press and release a System Access modifier key twice within two seconds, System Access passes the second keypress on to Windows, thus allowing the user to use Caps-Lock, Insert, Scroll-Lock, and NumPad 0 as originally intended. There is no conflict between StickyKeys and System Access Remote Training and Support functionality. Persons using StickyKeys can both receive and provide remote training and support.
