I'm new to Sublime 2 Text editor. I'm not, however new to programming editors. But I'm missing something basic about Sublime 2 plugins - how to use them. In particular I can't get figure out how to diff two files using the Diff plug in. I see that there is a Side Bar.sublime-menu file in the Packages/Diff folder, but right clicking on the side bar Open Files sidebar only shows a Close option. Right clicking on the Open Folders sidebar shows more options, but none of them are the Diff menu. The Diff context menu (Show Unchanged Changes) is active if I make a change in a file.
So what am I missing here?
