Hi PooMan - I would have done as you suggested but powering electronics off and on again repeatedly is not particularly a good idea. It is not at all conducive to extending component lifetime.
As I have a 30 inch monitor, blanking the screen does save a noticeable, but small, amount of power. But that is not my main objective. In my particular case my computer/monitor is mounted on a desk with my 61" TV behind it so I am very often wanting to blank out the monitor without powering it down
so I can shift my attention from the computer screen to the TV and not be distracted. Then, at a moments notice, switching back to the computer screen, if you see my logic.
This new shortcut, as suggested by Kari, works great for my purposes.
