Depending on the control, it might cone with their own short cuts.

On personalize interface, do the two show up as a single large monitor with both combined?
Do you have any software installed for the video card, like Catalist ?

Right click an empty space on the desktop, select "Resolution", and then you can change all those settings.

in response to arnold, on start up, the 2nd monitor has the exact copy of the first monitor.  Originally I could only show on Mon 1, then on Mon2, start something else, and both independently working at the same time.  I have lost touch how i got it to work that way.  one way was to hit the windows key + P, but this combination for some reason does not work any more.  That was how i got to do it. Thank u.
What is the brand name of the graphics control?
The change in shortcut behavior aside, what is the issue you wish to resolve/address.
Knowing which app/task would pop up, you can then navigate to it, under properties there is a section dealing with setting a keystroke shortcut.
As I already mentioned, right click an empty space on the desktop and select "screen resolution". Here you should see both of the displays and change between "cloned" mode which shows the same output on both displays, or "Extend" mode in which case you can move the displays around each other to display in the way you want.

Sometimes as nobus mentioned you can also do similar things using the display card's driver utility.
