You can change that key combo to switch spaces. I changed mine to use command+arrow because while I have ctrl keys on both sides of my external keyboard giving me the ability to switch spaces with one hand, I don't on my internal Macbook keyboard. So when I'm out and about without the external I need to use two hands to switch with the keyboard since the one ctrl key is too far from the arrow keys on the built-in keyboard. I do, however, have two command keys on either side of the space bar, one of them being conveniently close to the arrow keys. Thus by using command+arrow instead of ctrl+arrow, I can do the switching one handed with either keyboard.
Small thing, but I've found with experience (and if you use spaces a lot, which I do) it just makes things a little bit easier.
