Yes, except the really nice thing about %%%{PBXSelectionStart}%%% is that it gives me a unique identifier with 99.99% probability. For example, say that I wanted to hone in on where an exception was being raised. I'd pepper the suspect code, even if spread across different files, with NSLogs including %%%{PBXSelectionStart}%%%. Each one takes only one keystroke. Build and run. Console will print out something like this:
145656
145856
12674
12874
13476
*** Exception Blah Blah.
13487
Bang. Just do a ⇧⌘F, copy that 13476 to the search field, and in seconds the problem is staring me in the face.
__FILE__ would be useful if it didn't print out the whole damned full path.

My script deletes the entirety of any line that has the signature comment. Since C allows more than one statement on a line, I can also put in other temporary statements such as
thatString = @"Try this string!" ; NSLog(…) ;
and my remove-debugging script blows away all such lines with one keystroke.
My signature comment is: /*DB?Line*/. A regex like this should work:
[^\n]/\*DB\?Line\*/[^\n]+\n
Unfortunately, I remember learning once that Xcode's regex does not parse newlines, and just confirmed that still seems to be the case. So the \n on the end breaks it, and without it, I'm left with a blank line.
But thank you, Scott. I'll keep trying.

Code Snippets would start to fill the bill if there were some environment variables available.
