The AutoIt MouseDown Function is used to perform a MouseDown event, which can later be released by a MouseUp event.
If you want to make a selection, or perform a mouse drag and drop operation, then consider using the MouseClickDrag Function instead.
This function only takes 1 parameter, being the button to press down.
