I came across this when i was curious how much more rested xp i had on this character, as I'm currently leveling multiple teams and want to do it as efficient as possible. I use a mod for my action bars and have no real clue how to display this (don't even know if this is visible in the default interface).
Anyway, make a new macro containing this this line
Simply drag it on the actionbar and click on it. As i find it handy i though to share it with my beloved multiboxing friends :PCode:/script DEFAULT_CHAT_FRAME:AddMessage(GetXPExhaustion());
Note= obviously it will only do something _if_ you have rested xp left.
