cmd-J jumps to the editor, but if you have more than one editor open you get an overlay that has all of the open editors. you can use cmd-→ and cmd-← to switch between the open editors.

hide and show utilities: cmd-opt-0
Things that are commonly hidden here that aren't intuitive:
- data model entity properties.
- data model properties
- xib properties
