Remarks
Mouse events
are placed in the input buffer when the console is in mouse mode
(ENABLE_MOUSE_INPUT). 
Mouse events
are generated whenever the user moves the mouse, or presses or releases one of
the mouse buttons. Mouse events are placed in a console s input buffer only when the console group has the
keyboard focus and the cursor is within the borders of the console s window.
