For best results, you should put the script in the Tex-Edit Plus Scripts folder. Open the file called testTrack and run the script. It's that easy. Future plans I'd like to support the other descriptors, such as chromakeyed text, text boxes and so on. I'd also like to provide a simple interface, so that people can adjust the size of such things, but I'm still thinking about the best way to do this.
Suggestions are welcome.
Tex-Edit Plus at all. Tex-Edit Plus has a wonderful dictionary which makes the manipulations of styled text a breeze. I shall be looking into the standard Applescript commands, or perhaps an OSAX for manipulating styled text, so if anyone has any tips about this, please let me know .
