Thanks!  I can see I'll need to print out that list of commands....it's kind of long. It'll take a while to internalize those.    I was experimenting with the controls and got tired of making a mistake, shooting or choking someone, and having to reload.   
    I do want to give this game a try.  It runs beautifully and I've heard so many good things about it.  
EDIT:  I should have said that the XBox controller I have works on this game; I just couldn't figure out the controls.
