Key event processing

Input processing begins when you press keys on the keyboard.

The application must have created an IMObject before calling these functions:

IMFilter
Asks the IMED to indicate if a key event is used internally. If the IMED is composing a localized string, it maps the key event to that string.
IMLookupString
Maps the key event to a localized string.
IMProcessAuxiliary
Notifies the input method of input for an auxiliary area.
IMIoctl
Performs a variety of control or query operations on the input method.
