I sit in your hand and help you play, I move in all directions, left, right, or sway. Push me forward, pull me back with care, I control the action in a digitallair. What am I?

I am a long, silver snake that bends but never breaks to bite. I spend my days gripping twins, triplets, or crowds, keeping them in perfect order. If you strip me of my second half, I am just a daily read. If you strip me of my first half, I am a trim or a movie scene. What am I?

I do not speak, yet troops obey, My metal voice can lead the way. No strings or keys are found on me, Just breath and brass for all to see.

I get dirty with every meal, but I'm always disposed of with zeal. What am I?
