What do you want the macro to do?
could be as simple as:
/p Raising <t> <se.1>
/ac "Verraise" <t>

That'll make a beep and show who you're raising. Push it after you've pushed swiftcast or have a dualcast ready.
But healers are likely going to try and swiftcast a raise too, it's more their job than yours, so maybe give 'em a second.
