Strafe/peak Binding key
 

Sorry to mention this even if its been out since a long while, but how can you strafe and peak at the same time (and on the same side) only by using the strafe keys?

Is it a mod, a patch or some sort of binding key?
If so, can someone please post a link to it, because i can't find it anywhere on this site...

Thanks!

bind a "+moveleft; +leanleft"
bind d "+moveright; +leanright"

Just type that into the console.
