Sometimes, macros are usefull and this is one example for hunters. The macro below will take whatever item that is in slot #1 of your 4th bag (the one all the way left) and feed it to your pet!
- Feed pet -

/script if (not PlayerFrame.inCombat) then if (not
GetContainerItemLink(4, 1)) then OpenBag(4); else CastSpellByName("Feed Pet"); PickupContainerItem(4, 1); end end

I hope your not lazy because if you want to understand what macros are and how to make em, I advice you to read
www.wowwiki.com/Macros

it has a very clear explanation plus a set of examples of useful macros, Macros make things easier for you, like madjammu said, it can save you alot of time and trouble, no need to actually know programming to make em, if you read a couple of examples you should get the hang of it
