How to create a new Snippet in TextMate 2's Bundle Editor?

I'm looking at an existing Bundle in TextMate 2's Bundle Editor. **How do I create a new (editable) Snippet in the currently selected Bundle?** Seems like this should be obvious, but I am stumped. Searching the Main Menu contents doesn't reveal any menu commands which would obviously allow Snippet creation. Right-clicking in various related areas of the UI (in hopes of opening a context menu) has proven fruitless. Isn't there a way to create a new Snippet inside the TextMate 2 app itself (presumably in the Bundle Editor)? Or do I have to edit plist .tmbundles to create Snippets? I could have sworn you could easily do this in TextMate 1. The official TextMate docs seem to be version 1.x-specific.
