While this is a beautiful interface, I often read things like "traversing a long source file trying to look for a specific method’s implementation" or "sick and tired of having to scroll through a raw copy of jQuery..." and am confused. Why don't more people use their text editors' search functionality to find a specific piece of code? I never find myself scrolling through long source files.

The problem is, with jQuery specifically, not all functions are declared in the conventional fashion. E.g. trying to find the "height()" method is quite hard with a simple IDE search tool -- look how its defined: http://gist.github.com/291542

It's easy when they're declared as "function name(){}" or "name: function(){}" (in an object) .. or even "name=function(){}" ... but beyond that, it's simply not worth using your IDE's find tool.

Ideally one could use a proper IDE for this purpose but then OP has touched a good point; and IDE higlighting the calls of methods those are declared in the module would really help in understanding the source. I'm definitely stealing this! Thanks.
