The feature currently supports syntax highlighting for C++, C#, HTML/XML and LUA.
Using the new featureNotice two new available options in the Post Topic pages.
Clicking "Syntax Highlight" gives more information.
The green column on the right is the text to specify the code language.
I hope this gives a good demonstration of how to use this new feature in your posts and gives some nice color to your code examples and snippets. I am looking forward to seeing your colorful code, and as always feedback is welcome and appreciated.
