Installing windows 7 on Acer Aspire 5920

I am about to install a copy of Windows 7 on an acer aspire 5920(formatting the drive first), it is currently running on windows vista, I was just wondering if any knows if this will affect the functionality of the 'hotkeys' on the laptop, and if so will the windows 7 drivers from the acer website restore their functionality as I do not want to lose these keys.
thanks,
Eamonn
