there is no complete, up to date list. and until all developers agree to
some standard, there won't be.
I was the one to put up the flossmanual list page, wich is a smaller
version of the file in my pd member page,
http://puredata.info/Members/jmmmp. maybe in the next flossmanual sprint
there might be a new version of this list - which is made through
copy-paste, so as you can imagine, it takes a while.
I generally use the flossmanuals page http://en.flossmanuals.net/PureData/ObjListIntroduction#
I'm not sure how complete the list is, but I generally go to the page of
the category I think I'm looking for and use find in the web browser to look
for a key word in the function description.
