And the beauty of it is that all the hyperlinks are active unlike a PDF. It makes getting around so much easier than the PDF which is just a big searchable text document.
I learned on thing just recently:
click the little arrow in pdf search field
Select the full reference search or similar
then there is advanced search too
You get a nice list of spots to just to, like search in windows help files(chm stuff).
But manual itself is really not the best resource, so far.
Sonar.chm is the one to download(or pick from installation if you installed tutorials too).
