Center Click Trigger
There is no built-in trigger for the middle mouse button. If you are willing to use some JavaScript, you can do something like the following.
This example watches for the click event on specific objects, and checks to see which button was used. If it was the middle button, it toggles a variable in Storyline. You can then use the "variable changes" trigger to do whatever you need to do. Just create a variable for each object you want to monitor (labeled "triggerMidClk_[object]" in the example).
Much of the JavaScript code is commented out, and is for disabling default button behavior in the browser. You may or may not need it. It is not needed for this example. This worked in Chrome and Firefox.
Note, if you enable the code inspector in Chrome or Firefox it takes over the middle button actions, so this example does not work while the inspector is open. You can use the built-in inspector in Storyline preview and it will still work.
