Editing WoW:API CastSpell (section)

==Note==
Use "spell" or SpellBookFrame.booktype as the spellbookType for any non-pet spell. The id is counted from 1 through all spell types (tabs on the right side of SpellBookFrame). Pet spells also start from 1. (See example above). The CastSpell function can not be used outside Blizzard-signed code except when "casting" trade skills (e.g. Cooking, Alchemy, etc.).
