Belgian keyboard when in console

[jandebacker-heist]

To copy the USB installation towards the hard drive, we have to go into command and typ this:
/usr/sbin/chromeos-install --dst /dev/sda

In our country we use a Belgian keyboard (AZERTY), but the console is in American QWERTY. Therefore we have to type this:
/usr/sbin/chro,eos-instqll --dst /dev/sdq while the display shows the correct command.
On a laptop without a numeric pad, it is even worse, because the - and / are on a different location. Then it is like this:
=dev=sbin=chro,eos)instqll ))dst =dev=sdq , still giving the good result.
Is there a simple way to set the keyboard to Belgian when in console, so that we can type the command normally?

Thanks
