I've recently moved to InDesign3 from Pagemaker. I have some pretty elaborate scripts in PM that I need to reproduce in ID3. In PM there was a list of all the available scripting commands and their required format. I've been looking and haven't found anything similar in ID3. Is there a list of available commands other than the sample scripts?
There's a list for CS2 here: http://www.kahrel.plus.com/indesign/id4-dict.html. It highlights the new script commands for CS2 (InDesign 4), so if you ignore those you get the list for CS (InDesign 3). If you're on Windows, you could also use Teus de Jong's object browser (http://www.teusdejong.nl/, pick "InDesign utilities").
