/clearfocus
/focus [target=toon1, exists, nodead][target=toon2, exists, nodead][target=toon3, exists, nodead][target=toon4, exists, nodead][target=toon5, exists, nodead]

Ok so this macro sets the focus to toon1, toon2 etc etc

So what does setting focus do?

Probably a better question is how does this help?

Do you /assist or /follow after you set focus so with this macro if your team gets split up they can follow or assist eachother? Or if someone dies they will just start assisting off toon2 etc?
