Well, they are not in the official quick reference either. I found them on 
the documentation, but I won't search everywhere to list them.
I would be interested by such a list, though, we could highlight them in red 
to warn they are obsolete.

Well, I am not so ambitious, I just want to make a syntax highlighting lexer 
for Scintilla. Which shouldn't be a big task, as I will derivate it from the 
already existing C++ lexer.
