Good post. I would like to know this too.
Look to the thread on this forum with the unofficial "bind" faq. That FAQ explains this quite well.

Cool! Thanks.
When I tried it myself, I was using the word "ally" instead of "friend".

Greetings. Here is a simple question that I hope someone can answer. I have been playing around with the /bind command and one of the binds I have made is to "target nearest enemy". I find that really handy to be able to target whoever is closest to my Blaster so I can get the enemy out of my face.
With my Defender however I would like to target other players to see if they need healing. So my question is: Is there a key in the game already to target nearest ally (not someone in a team, just target ANY player)? Or is there a way to set this up using /bind?
Thanks,
MW
