As I said, the questions are super easy, a third grader could answer them.
I found some variables but doubt they will help me.
isnavi will return 1 if the message was sent in the navigation server, and 0 if not, in the example: $curmsg.isnavi will return '0' <======== what's the navigation server?
isaction will return 1 if the message was an action (like the 'Ahhh...' of mana potions), and 0 if not, in the example: $curmsg.isaction will return '0'
