Is there a way to sort a BibTeX file from within TexShop? For instance, I would like to have all items of type @proceedings at the end of the file, and the items otherwise sorted alphabetically (say by the name of the first author).
I'm not referring to sorting the references in a compiled document (using a .bst style), but rather the BibTeX entries themselves in a .bib source file.
I used to be able to do this on Windows using WinEdt. Can I achieve something similar in TexShop on Mac OS X?
