How do you customize sounds? System preference shows the different sounds but how do I apply those to certain actions? i.e. The trash can makes a sound when I drop something into it. How do I change that sound? Once I get that down I'd like to learn how to add custom sounds that didn't come basic. I have an iMac and I'm running Tiger (I know it's a stupid question, but I'm new to Apple and I'm MS conditioned) Thanks everyone.
