4 must know wordpress links

Hi there; while working on my first wordpress theme I stumbled upon the following pages which I found and still find very useful as quick references.

1) http://codex.wordpress.org/Template_Tags

2) http://codex.wordpress.org/Function_Reference

3) http://codex.wordpress.org/Category:Conditional_Tags

4) http://codex.wordpress.org/Plugin_API/Filter_Reference

Make sure you keep them in your favorite list; I know I already did.
