There is a "package control" plugin, but it is not obvious how to use it.

The tutorial below mentions how to install and use it
I almost see it as a "must have" for sublime text to be used professionally.
CodeIntel autocomplete works very well, I was impressed with it, however it lacks the single feature that keeps me using eclipse.

I want to press CTRL+R (@<search> syntax), start typing a name of a function/class and have it take me to that file at the declaration point.

I also find myself unwilling to switch to sublime text 2 from my current eclipse+pydev setup due to the lack of this feature.
