strange notation in macros

[kate]

Blizz changed the way you can write macros now to save some space on the 255 character limit. the " @ " replaces " traget= " and for Player.. you put in the Player's name.

Ex: you want to cast Renew on your Paladin, named Joe

/cast [@Joe] Renew,,,,

"Player" can also just be used to target yourself when not swapped for a name.
