Star Wars Battlefront commands??

[Byte 2.0]

I have been playing Battlefront online and it is much different then playing against the computer. One of the very useful features in multiplayer is the ability to lay mines or hand out heath and ammo.

Problem, when I am playing one of the characters that has those abilities, i am unable to do those.

I have primary fire on right click and secondary fire on Left click.

But which command is the 3rd item like Mines or pass out ammo or health? I will probably have to assign a new key to it, but I need to find it anyways so I can configure and use it.
