Other issues I've been having:

The following macros don't work:

/cancelform [nomod:ctrl,mod:shift]

^Character A

/cancelform [nomod:shift,mod:ctrl]

^Character B

If I hit movement keys, my second character whacks out and either starts spinning or automoving in the direction I hit.

Also, I'm trying to decide which of the following macros will work properly in allowing me to auto assist my main on my first cast (because I keep forgetting to assist them beforehand):

#showtooltip [Wrath]
/target [help,party2][notarget,party2]
/assist [help]
/cast [harm] Wrath; [help] Rejuvenation

#showtooltip
/assist Character X [mod:X]
/cast [harm] Wrath; [help] Rejuvenation

If you have another suggestion for the above, feel free to let me know.
