OK, i figured out how to make this work. Thank you for this command i never knew Miko, but you left some bits out hehe.
Here is what I have on my PLD now, i will break it down for any other Googler who finds this page:
Code:
/macrolock
/hotbar copy PLD 2 LNC 2
/ac Hallowed Ground
/hotbar item "Phoenix Down" 2 6
/macroicon "Phoenix Down" item
/p Emergency Phoenix Down Raise on <t> with Hallowed Ground! <se.10>
/wait 5
/hotbar copy LNC 2 PLD 2
Note the second line. You must have a class or job you aren't using, to serve as your "bar bank." First copy sends my Paladin's Hotbar 2 to Lancer Hotbar 2 - this is the bar that has my macro on it.
I then CHANGE this button to be the Phoenix Down, as Miko describes. In this case, my paladin's Bar 2, Slot 6.
Note that instead of the <wait> command, which as Miko says will give you a split-second to click the PD - the slash command /wait 5 gives you, you guessed it, 5 whole seconds before it changes back to the macro. Heck you could make it longer if you want to, it's not like you'll need this button again for another 6 minutes, right? =)
Lastly, I copy the saved bar BACK from Lancer 2 to Paladin 2 - restoring the button slot 6 to the macro again.
It doesn't matter that Lancer cannot use 90% of what I sent it, i'm just using it as a temporary holding place for my bar; and I do not play Lancer; so there you are. Hope this helps anyone else trying to get this to work.
Final thought: for bonus points, can anyone think of a way to make this universal, instead of needing one per job?
Obvs the PLD one using HG is for PLD only. BUT,
Is there some variable we could use for "this job's bar X slot Y" instead of specifying the class? If there is, then you could just keep some class as your macro bank, and always pull from it to "this job," and need far fewer macro variations to do it.
But, even if not, this is still pretty darn cool.
