Trigger on click

Firstly, great plugin mate, very well done

I have got it working nicely with contact form 7, but i was wondering if it is possible to change the trigger to be on click, rather than elapsed time.

e.g i have a button on my page that if clicked triggers the pop up.

i am fairly adept at changing css/php code so if it is possible with your plugin could you direct me to where/what i would need to change?

Thanks in advance
