void HookKey(int scancode, system script)
-----------------------------------------
Binds an event to a specified keypress. This allows you to create menus and
other types of key-based events easily.

ex: HookKey(1, Menu);
When Escape is pressed (key scancode 1), the function Menu() in system.vc
will be executed.

See also: HookTimer(), HookRetrace()

Example:
HookKey(1, menu_script);
