The following placeholder commands are also available.
The only commands that can be used to designate targets are <t>, <me>, and <st>.
<r>, <p0> through <p14>, and <lastst> will display the respective name in the chat log, but cannot be used to designate targets.
Same deal from beta...it makes it very difficult to target. <ST> works but, they should allow you to cycle through the party list bar to make targeting easier. <ST> will select the nearest target and sometimes you have to target around a lot to find the person you are trying to heal and it becomes very frustrating. For now, I did what was doing in beta:
/action Cure <me>
This turns AoE on before the cure, casts cure, then turns AoE off. There isn't any need for waiting that I found, even though the chatlog will say that AoE is turned on and off before the cast of the spell, it still goes through as AoE. I do these for most of my buffs such as Shock Spikes and Stoneskin.

Seriously, you won't be @#%^ing happy until SE releases a full sized Bahamut avatar you can @#%^ing ride and use to kill players that annoy you, one shot AV/PW/Shinryuu, and burn the FFXI nations to the @#%^ing ground for fun. All while actually restoring mp used instead of costing any.
