Questions on Bbot scripting, come in and help

[Bbotone]

I've not seen this language of macro variable set, in bbot wiki documentation, but i've seen in some script on the website:
X:=Target.Distance
Is there other macro commands that isn't explained in wiki?
---------------------------------------------------

Misc.LoadUrl(Url) load a URL (advanced), what does this command do?
---------------------------------------------------

Concerning these commands,
It seems that there are 3 definitions of target which confuses me:

1: Targeted monster in tibia client(red boxed)
2: Targeted monster set to be killed by Bbot's Killer
3: Targeted monster defined by Target.Foe or Target.ByName(Name)

These 3 definitions will be refered as Target1, Target2 and Target3 in my questions below:

Target.ByName(Name) targets a creature with the name.
Targets creature as Target1, Target2, or Target3?

Target.Foe targets the creature you are attacking.
Will target Target2 or Target3?

Target.Self targets yourself.
What does this do to my character?

Target.Health returns the target hp (in %).
Target.Speed returns the target speed.
Target.Distance returns the target distance to your char.
Target.NameIn(Name, Na..) returns 1 if the name of the Target is in the list.
Target.Shoot(Ammo) shoot a item in the target (sample: ID '3155' shoots a sudden death in the Target).
Target1, Target2 or Target3?

Self.AvoidFront makes your character avoid waves from the target creature.
Target1, Target2 or Target3?
Is it bugged? When I set the command: < 2500 {teste2} Target.ByName(Spider) Self.AvoidFront > It will move to avoid front once, and won't avoid front anymore

Self.AvoidBackboard makes your character run from the target creature.
Target1, Target2 or Target3?
Is it bugged?

Self.Attacking returns 1 if your char is attacking.
Attacking through Target1, Target2 or Target3?
