It happens all the time. You change your multi-monitor configuration in some way and now there is a window unreachable off the side of the screen. Way out in right field your Skype buddy list is napping, or even your web browser. This is because applications try to be intelligent and remember their last location for next time they are used.
The first step to resolution is admitting you have a problem. You open a new web browser and it is nowhere to be found. But you can see it in the task bar. Clicking on it multiple times you can see it restore with a ghostly visual queue that it is going up and to the right where your monitor used to be. Aha! Now you know where the little devil is, you can begin the work to reeling it back in. Right click on it in the task bar and select “Move”. This allows you to move the window using your arrow keys.
But what if you do not have a move option? No problem. Alt+Tab till the desired window is selected, Alt+Space Bar, then press “M” for move, Press “Enter” when the window is finally in view. This works for Skype and many other programs which strip the “Move” option from the task bar menu.
Very handy little tip! Never knew about the Alt-Space trick, nor that you could move windows using just your arrow keys.
However, I would like to point out that once you’ve select Move from either the right-click context menu or the Alt-Space M trick, the mouse is put right on the window’s title bar. You can then just click down with your mouse and drag the window into view, which may be a tad bit faster than using the arrows keys to slowly shift the window around.
If the window is off in a non-existing monitor the mouse does not make it off screen to the title bar, so your second suggestion is unable to work. But the suggestion works but you still must use the arrows.
