Simple jquery function question [solved]

Simple jquery function question [solved]

I'd like to ask what the "e" in the following function is for and where can I find the documentation on how to use it.

$('a').click(function(e){
       //what is the "e" in "function(e)" and how can I use it?
});


Hope you can help me out as to what it is, what are it's properties/methods, and where is it used? I find this really interesting.
