That also works the other way around -- you can use alt+control instead of right alt. This may make sense to do with some of the more annoying key combinations

That also works the other way around -- you can use alt+control instead of right alt. This may make sense to do with some of the more annoying key combinations, e.g. the German layout requires pressing AltGr+7 for '{'. Both keys individually are usually pressed by the right hand, but pressing the combination with the right hand alone is a very uncomfortable hand position.
