[Harry Potter] Does "riddikulus" have any other uses or is it specifically for turning boggarts into funny things?

On some level, this exercise is a lesson in overcoming fear.  It's sort of the same as people telling you to imagine the audience naked to overcome stage fright.  You wouldn't necessarily cast riddikulus when you're facing down a dark wizard, but the overall lesson you're learning here is how to operate *through* an episode of fear and that might come in handy in a situation that might otherwise be fairly paralyzing.
