Spawn bind

[telepreto]

Hi!

this is my problem,
i don't have a bind to the spaw menu,

for example my friends that play this game, they all press the return button and the spaw menu appears
( even when they are a live and they change squad and that stuff without need to be dead)

well i just can't do that
i press return and nothing appears i tried to search on the control options for that button but nothing appear :S
i already try the option " reset to default" and nothing

can you help me?
