Hi there,
Go into the Game go to "My F1" then Options, scroll down until you see the commands for
Menu Left
Menu Right
Menu Up
Menu Down
Assign them commands to your arrow keys , then ingame push the Arrows to access your management... for example,after assigning them keys ingame if i want the engine to go fast , i push Up Arrow then the Right Arrow and then the Up Arrow again to select my engine to go into "FAST" mode.
