[jitter] looking for complete Jitter Javascript reference

Hi to all
Maybe I'm missing somehting (probably) but.. After many years of avoidance, I'm finally trying to learn how to work with javascript in jitter, and can't seem to find a reference of all the available properties and methods anywhere. I picked up bits and pieces from the example patches, the "javascript in max" pdf, etc., but still can't find some essential stuff, such as how to change a matrices dimensions, srcdim and dstdim, etc. I knew there was a reason I preferred graphical programming! Any pointers to the info would be appreciated :)
thanks
