-- Em3270UserInputDefs:  3270 Emulation User Input Handler


--  Revised for Star 3.0adrTI  by Lui:		        30-Jun-83 14:07:39
--  Owner:  Kernaghan

--  Overview:
--  This module will handle all user inputs to the emulator coming from the Star world, that is, from the Notifier.  These inputs come from either keystrokes or mouse actions.
--  It is responsible for determining what action has taken place (keystrokes or mouse) and then executing the function of that action, for example, processing AID keys, reseting the cursor at the mouse position, inputing characters fron the virtual keyboards, inhibiting the keyboard,etc.
