[TxMt] A Way to Dump Scope?

[Charles Turner]

Hi all-

Is there a way to dump the current scopes out? I'm thinking like the 
"Show keyboard shortcuts" in the TextMate bundle?
Or is there something that documents the relationship between the 
various scopes, and the syntax colors?

For example, there's an appearance attribute named "Preprocessor 
Directive", but what scope would lead to something being colored with 
that attribute?

I think also I've noticed some conflicting documentation: Is it 
<comment.block.documentation> -or- <comment.documentation>?

Thanks as always, Charles
