Make use of macro's.

One of the best things of World of Warcraft are the macro's in the game.
They are usefull for Prospecting, Disenchanting, accepting things for Auctioneer but also for reloading the UI.
Here are some examples wich you can use:

Prospecting:

/cast prospecting
/use Saronite Ore
/use Titanium Ore

Disenchanting:

/cast disenchant
/use Simple Opal Ring
/use "item name here"

Milling:

/use milling
/use lichbloom
/use adder's tongue
/use icethorn

Auctioneer (accept the confirm message)

/run if (AucAdvancedBuyPromptYes) then AucAdvancedBuyPromptYes:Click() end

Reload the UI (usefull if you have more then 50 mails waiting)

/reload ui

You can fill in the macro's at ESC > Macro
Put them at your action bar and make your daily routines alot easier!
