If you’re using PSPad for viewing .qc files (the text file needed for compiling assets for Source), try out my custom highlighter. To use it, take out the .txt extension and copy it into [Program Files]\PSPad editor\Syntax\. Once in place, it can be loaded through PSPad in Settings->Highlighter Settings and assigning it to an available slot. For those using a fancy text editor other than PSPad (shame on you!), and want to make your own QC highlighter, check out the example here (ConTEXT) http://bit.ly/dkbCtY.
