Thanks for all the responses. Actually, I am the boss. There are times when I have to quickly minimize an app if it contains something confidential (personnel issues, security plan, etc.). I have to suddenly reach for the mouse, making it obvious I am hiding something. Although this is sometimes necessary, especially with respect to many business issues, it is just better not to be obvious about it. It just would be nice to be able to quietly push some hot key to do this.
