Beginner questions about articles in Xaraya

Hi there,

I fear that my very simple questions will completely humiliate me. But 
reading the manual has not let me work out how to do some very simple 
things... so here I am with some questions. Feel free to laugh at me, 
but please give me some tips after you get your breath back  ;-)

1 How do I display an article?

2 How do I display all articles of a particular catagory?

3 How do I display all articles of a particular publication type?

4 How do I display all articles in several catagories?

5 How do I display all articles of several publication types?

These questions might seem mind numbingly obvious to you experts. But as 
a newcomer to Xaraya with only understanding of how PostNuke works and 
no PHP programming skills, my small brain can't work it out. So please 
give me a (typing) hand and perhaps these can go into the docs along 
with the VERY HELPFUL new Overview which was added into the docs due to 
my silly questions here last week :-)
