A short answer: \r is the carriage return, Ctrl-m, dec 13, hex 0c, oct 
15 as used in Mac OS, while in Windows and DOS it as accompanied by the 
linefeed \n, Ctrl-j, dec 10, hex 0a, oct 12, which is usually used in 
UNIX to end a line.

There might be some more in Help. TeXShop uses OgreKit (the OniGuruma 
Regular Expression Framework for Cocoa) as engine for regular 
expressions -- because TeXShop is built for a world wide 'market'. 
There is probably documentation about it on the web. Last year I found 
only a Japanese site with a button to translate all in English ...

As far as I remember both BBEdit and OgreKit use a syntax that is close 
to what I am used on the command line or in GNU Emacs. I had to 
practise and was glad of undo -- and of closing the window without 
needing to save.
