How Do You Do Half Jumps?

[Zutto]

I seen a lot of people playing do half or quarter jumps, how do you do them? My jump is spacebar and each time i push spacebar, it does a big jump.

Thanks in advance.

its a combination of Space + Ctrl.... you gotta time them right. also the forward and backward keys play a role in it.
if ur talkin about the walkin jump that ppl just lately realised.... they use the mouse
type this in console

bind "mwheeldown" "+duck"

and use the mouse wheel down for that.
