hello:)
TeXShop can provide synchronization in two ways.
"pdfsearch" : The default method uses a new ability in Mac OSX 10.4 to search for strings in pdf files.
No special style files need be included to use this method.
"pdfsync" is the original method but needs to add the following line to the preamble of your tex source code before the \begin{document} line:
\usepackage{pdfsync}.
Is it to possible to use in the future, the first method "pdfsearch" with Textmate
Thanks
Alain
