# ** Keyboard Input Module
#==============================================================================
# Near Fantastica
# Version 5
# 29.11.05
#==============================================================================
# The Keyboard Input Module is designed to function as the default Input module
# dose. It is better then other methods keyboard input because as a key is 
# tested it is not removed form the list. so you can test the same key multiple
# times the same loop.
