binding strafe to cursor-keys

[Otsego]

Hello,

i have a question: is it possible to bind strafe left/right to cursor left/right?
I wont work ingame so i tried to edit keybindings_de_de.xml
but i have no clue which numer the cursor keys have and i am not sure if this would help if i changed it as it seems cursor keys are hardcoded but it worked in the past i am pretty sure.
