It is really difficult to directly go to some given command 
without having to look it up on the search box provided by the 
google index. Besides, having all the keywords in one place, 
helps a lot to newbies discovering the language, or so I think 
(just hit CONTROL+F and fast-find anything without knowing what 
section (contents) the keyword lives in).
