Oops! My bad. I figured it out. There is a loop icon in the program monitor. Set your in out, click loop, click play in to out. I guess I could set custom key board short cuts couldn't I. Sorry for the post.
You can set most of those by going to Edit > Keyboard Customization. They are in the main "Application" category.
Also, there is a new Adobe AIR app that lets you search for Adobe program shortcuts: get it here.
Awesome! Thanks I just downloaded it. You get the correct answer.
