How Do I Load Control Key Functionality On Page Load

I have a Jquery selectable list on one of my applications, if a user holds down the control key it allows them to select multiple items with out having to select them in a sequence.
I would like to allow the users to be able to use this functionality without having to press the Ctrl button on their keyboard
