How to navigate to the method declaration of a Ruby on Rails method in Sublime Text?

Question

I am looking for a functionality for easy navigation of source code.

Here is my problem to be specific:
I use Sublime Text, and I often tend to read the method definition of a lot of methods before implementing them, but for that, I need to go to the source code on GitHub and search for that exact location where the method is defined

What I am looking for:
I am looking for a functionality wherein, when I double click on a method, it should open the definition of the method at the same place, preferably in a new tab.

Example:

In Rails, clicking on the method before_filter should open the method definition of before_filter.

This is similar to:

⌘ + mouse-click

functionality in RubyMine. More information here.

I have referred to articles for CTags which do not seem to help.
