===== KEY SHIFT  =====

===== SYNTAX =====
     = KEY SHIFT

==== PURPOSE ====


The ''KEY SHIFT'' function returns the current status of the various 
control keys. These keys such as ''SHIFT'' or ''ALT'' cannot be 
detected using the standard ''INKEY$'' or ''SCANCODE'' functions. 
But you can easily test for any combination of control keys with 
just a single call to the ''KEY SHIFT'' function. The result is a 
bit map with the following meaning:

'''0 -LEFT SHIFT'''
'''1 - RIGHT SHIFT'''
'''2 - CAPS LOCK'''
'''3 - CTRL'''
'''4 - LEFT ALT'''
'''5 - RIGHT ALT''

If a bit is set to a one, then the associated button has been held 
down by the user.

Note that not all computers support control keys, nor is it possible 
to have individual pressure detection. Depending on the target, 
some of the bits may not be available, or only under certain 
conditions.



==== EXAMPLE ====
    CENTER "Press some control keys"
    DO
       LOCATE 14, 4
       PRINT BIN$(KEY SHIFT, 8)
    LOOP


==== ABBREVIATION ====
   KySHIFT


==== AVAILABLE ON ====


==== ALIAS FOR ====
[[KEYSHIFT]]
