keyboard controls

hi im hoping to buy the game later today

just wondering though is there anyway to change the keyboard controls?
i ask this as my pc is in a bit of a mess so im looking to put it on my laptop however i dont have a num pad i have a decent mouse to plug in but no numpad untill i can afford a new machine
so will i be able to change the controls in order to drive the buses?

thanks
mike

In the options menu (keyboard tab) you cann assign each function to a new key.

ah thats brilliant thanks for your help looking forward to driving now
