PDF-TeX synchronization

Skim supports SyncTeX and PDFSync to synchronize between a line in a TeX source file and the generated output PDF file. To enable PDF-TeX synchronization, you need to setup Skim and your favorite editor to know about each other.

To display the TeX source line corresponding to a point in the PDF document, hold down the Shift and Apple key and click on a point in the PDF document.

To choose the command to open the TeX editor, choose Skim > Preferences, click Sync, and choose a preset editor, or choose Custom and enter a path to an editor command and arguments.

Check the Skim Wiki for more details, in particular about how to set up various editors to use Skim’s TeX-PDF synchronization.
