How to Inspect Rev Tools

[Dan Shafer]

The docs say (or strongly imply) that since the entire Rev UI is  
written in Rev, you can examine how it does things and even, given  
sufficient courage and backups, tweak the way the development  
environment works.

Pray, how do I do that? I can't seem to get any of the Rev tool stacks  
to open in an editable or viewable way.

What terribly obvious thing am I simply overlooking?
