Just as (in Windows platform web browsers) you can open a link in a new window by CTRL-left-clicking, you can also middle(mousebutton)-click a link to do exactly the same thing, and I had always assumed that both cases were treated identically by Google Analytics, and thus by your plugin.

However, having just spent some considerable time in Firebug, I have realised that my assumptions are false - middle-clicks are NOT tracked!

Is it possible to ensure that left-clicks and middle-clicks ARE both tracked without having to duplicate my calls to your plugin - i.e. to avoid having to initialise once for the [left]click event, and once for the middle-click event? Can you create a new option to allow this behaviour to be switched on, just as debugging can?

And can you please make it clearer to other potential users that middle-clicks are not tracked by default?
