Sprinting And Strafing

OK I am back to my old keyboard, I couldn't get on with that merc stealth.

The problem I have (and have always had with this keyboard) is that I can't sprint and strafe at the same time whilst going forward.

I don't use the normal keys like most people, I use the number pad with my left had to all my moving.
2=forward
1=strafe left
3=strafe right
0=back

I use the right arrow key with my little finger when I want to sprint and use the mouse2 to jump.

OK so now I hope you get the picture.

Anyway, does anyone know how to enable the use of the right arrow key to sprint whilst I am running and strafing.

Or to put it another way, allow me to strafe left and right whilst I am sprinting and going forward.

FYI
All the keys on the keyboard are binds that are set to a way I can remember them.

e.g
A=I need ammo
M=I need Medic
F=Follow me
W=You're welcome
H=Hello
B=Bye

etc etc

type /+sprint in the console whenever you feel the need to run

I have the same kind of problem - When i'm holding forward, left and sprint down then i can't jump

The computer just beeps :/

Then how do you do your Trick Jumping ?

i type /+sprint in the console so i will always be running

I don't need to type /+sprint every time i start running, i just do it once (when i connect)
