Lightroom Arrow Keys for Scrolling Through Images. Press and it keeps scrolling

Hi all

I've had this on numerous Windows computers and am wondering if its normal behaviour and can it be adjusted.

If I am in Library Mode and I press the right arrow key briefly once it moves to the next image.

If I hold down the right arrow key for a few seconds it could scroll through hundreds of images and you can't stop it until it decides to reach the end. If you hold down the left key while trying to stop what the right key did it will after stopping go forward start shooting backwards at a rate of knots. 

Seems very stupid, I wouldn't mind if it jumped 10 or something but it just goes crazy fast through the images and lifting your finger doesn't stop it.
