how do I skip to the next trial with a click

[wanching]

Hi,
I would like to let my subjects skip to the next trial whenever they want. What I plan to do is that once they feel they are ready to proceed to the next trial, they'll click on a hyperlink and they will be led to the next trial. The reason why I don't want them to click on "continue" to proceed to the next trial is because I cannot predefine when they want to exit. Is there a way to skip to the next trial regardless of how many questions are unanswered?
Thanks.
