blender tool descriptions?

does anyone know of a website or something with maybe descriptions of all (or most) of the buttons and tools of blender because i am having a little trouble adjusting to the more advanced 3d functions that blender has compared to oh say anim8or. i get the basic stuff and could make just about anything i want, i would like to use it to its full ability though.

the socumentation is your best friend here - check out blender.org>>documentation>>… pretty much self explaining.
