Site warns when an external link is clicked

Why does it work only with the left mouse?

Hello everyone !

I am curious about one thing.. and maybe you can enlight me on this:

I know a popular website which has external link warning message when you left click on a link that takes you away from that website... but on the same website and the same link if you click with your mouse wheel (firefox) or right click the link and then select open in new tab (internet explorer) the browser takes you to the specific link and the external link warning message doesn't even show up ! and I dont unterstand how this is possible.
Thank you for your time , have a nice day !

Possibly they are using a onclick JavaScript function to give you the warning. Onclick is not triggered when you right click or use your wheel.
