If you like using TextMate for all your code editing needs, and are using the Confluence wiki platform, and you have TextMate set to work as an external editor in Cocoa apps (such as Safari), then this little bit of know-how may come in handy:
Confluence wiki markup looks suspiciously like Textile. In fact, yes, it is officially based on Textile markup. So if you are editing wiki markup in TextMate, set the language of the document to Textile and you’ll get all the nice color coding and formatting tools.
Best of all, the Function pop-up menu will find all your headings (h2., h3., etc.) and organize them into an indented menu for you, making long documents much easier to navigate.
