entering hypergeometric functions in maxima

Hello people,

I am new to Maxima so apologize for basic question.
First of all, I want to use hypergeometric functions in Maxima.
I am using Maxima 5.11.99cr2. 
I looked up the help and the only reference I found is '%f[p,q] ([], [],
expr)' in the paragraph '16.1 Introduction to Special Functions'.
Nothing more on this function, when I tried to use it, for example
ev(%f[1,1]([1],[1],5)); Maxima does not produce results, same with
plotting and so on. I know there is more function on hypergeom, like
hgfred to simplify the functions, I tried this one and works but I still
do not know how to enter and handle hypergeometric functions (especially
confluent). I could not find any manual online so please if someone
could help me or point to the right document I would be more than
grateful.


Regards,
Michal
