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.

never been a really good one, and even those that are most tolerable
are arbitrary, cruel, grasping and unintelligent. -- H. L. Mencken
