If you wanted to control the volume with the right and left arrow keys, the following modifications to the above code could be made.

this.onEnterFrame = function () {
if (myLoopVolume<99) {fadeIn01=1}
if (myLoopVolume>1) {fadeOut01=1}
//Increase Volume with Right Arrow Key
if ( Key.isDown(Key.RIGHT) && fadeIn01 != 0) { 
  _root.myLoop.setVolume(myLoopVolume); 
  myLoopVolume=myLoopVolume+5;
if (myLoopVolume>99) {fadeIn01=0}
}
                                              
//Decrease Volume with Left Arrow Key
if (Key.isDown(Key.LEFT) && fadeOut01 != 0) { 
  _root.myLoop.setVolume(myLoopVolume); 
  myLoopVolume=myLoopVolume-5;
if (myLoopVolume<1) {fadeOut01=0;}
}
}
 

The Flash example in Fig. 09 also allows for the use of the Up and Down keys to control volume.
