Sublime Text 2 - Link with Editor / Show file in sidebar

Just right-click anywhere in the file's view and press "Reveal in Sidebar."

To make a key-binding, go to Preferences > Key Bindings-User and add:

{ "keys": ["ctrl+shift+r"], "command": "reveal_in_side_bar" }

You can install this via the Package Control utility (although it doesn't mention it on the github page).
