Force Mouse to Center of Screen?

I have an annoying problem.. I have multiple 27 inch monitors for use with stock trading and autocad use.. When I'm not actively working and not trading stocks or doing autocad work, I turn off my other monitors (save energy) and just use the one in front of me..
The problem is that sometimes my mouse cursor gets lost on one of the inactive monitors and I have to move the mouse in big concentric circles until I see it appear on my main screen.

Is there an "F" key or other keyboard way to get the mouse into the center of Monitor No.1 ????

UPDATE: Found a little script someone posted that does the job quite well..

CenterCursor.ps1
[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") | out-null
[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") | out-null
$bounds = [System.Windows.Forms.Screen]:rimaryScreen.Bounds
$center = $bounds.Location
$center.X += $bounds.Width / 2
$center.Y += $bounds.Height / 2
[System.Windows.Forms.Cursor]:osition = $center
Save this script in a convenient folder, and create a shortcut in your All Programs menu:
Now whenever you press Ctrl+Alt+Shift+C, your cursor will return home.
