Searched here, wow forums, and google. Wasn't sure what key terms I needed (party1 and such gave me hundreds of macros)

How do you determine:

party1
party2
party3

Keys 1-5 are associated with the party number.

Is there a way to determine Key 1 will always be [target=party1]

Screenshot attached to see if this is correct:

Tweadledee (my druid) is included the party for dualboxing & targeting purposes.
