Attaching Sound to Keypress

Hi, making a drum simulator in Flash MX, how the hell do I attach a sound to a key press. You would think it would be as simple as, " On KeyPress(whatverekey) play sound", but I cant seem to figure out. An help will be appreciated. (By the way, I want to attach the sound “highhat_closed” to keypress <Page Up>, <Home>, and <Insert>)
