In Eclipse you can jump to definition/declaration by clicking on hyperlinks with pressing command key (control for Windows). I would like to use the same functionality for Sublime Text 3. Mostly I work with Robot Framework with a lot of files and would like to jump to the source of Keyword through whole project.
In sublime this kind of feature is provided by plugins.
Look at https://sublime.wbond.net/packages/Robot%20Framework%20Assistant or https://sublime.wbond.net/packages/Robot%20Framework, but be aware you can't use both, they conflict.
