Just [d] means "d" or "D". Just [3] means "3". There is no [\d] digit or 
\w alphanumeric like in regular expressions, there is no "{4}" or "+" 
for repetition.

These patterns are not regular expressions patterns, but still offer 
flexibility and are easy to understand: * = "zero or more of any 
character" and ? = "exactly one any character".

You can have more than one pattern or page name, join them with commas, 
eg (:if name *-Users,*-Talk:).

And you can have negatives, place a minus before a page to be excluded: 
(:if name -*-Users,-*-Talk:).

The brackets are for more advanced usage.

Most people will probably simply need a page name without a pattern, 
like (:if name HomePage,SideBar:).
