Do someone knows a way to get Quest ID?

[adriancs35]

Hello, recently I started playing on a wow 4.3.4 server. And i saw that quest swapping is possible.Do someone knows a macro to find the ID of a custom made quest?
Is simple to find item IDs

/run SLASH_ITEMID1="/itemid" SlashCmdList["ITEMID"]=function(msg) local _,link=GetItemInfo(msg) if link then ChatFrame1:AddMessage(msg .. " has item ID: " .. link:match("item%d+):")) end end

But do someone knows a macro for quests?
