[FMX] Creating a Ctrl Click

Is it possible to detect a key press along side a mouse click eg

A movie clip clicked
Click = false 

But if the same movie is clicked whilst holding down the Ctrl key 
Click = true

Basically its an action listener for the control key.

What is the best way to do this (when I say best I really mean easiest)

I will be using this in a jigsaw puzzle scenario and when a piece is Ctrl Clicked the piece will rotate but when its clicked regularly it will just follow the mouse.
