Apple :: How To Move The Active App On The Screen With Shortcuts

How do I move the active app on the screen with some keyboard shortcuts?

I really need some application that will move my windows where I want right away, resizing them at the same time.

My specific scenario is: I use an external 27" LCD with the MBP; I keep connecting and disconnecting the laptop over a day at work several time.

The problem is: I set up a window to be "that big" and to be on "that" part of the display, I set up other windows next to the first one (usually all documents, need to compare them side by side) and it looks and works fine on the big screen, but when I disconnect they are not keeping the side-by-side position (smaller of course, to fit on the 15" MBP display).

My wish: to press something like Ctrl+1 to move the active window to position 1,1 on the screen, with the windows size of 960 & 600; Ctrl+2 to move the active window to position 961, 1, with the size of 960x600. This way I would get the 2 windows side by side really easy.

I found several apps doing this(and much more) for Finder, but nothing for any window of any application that runs on Mac ...

I have no idea how hard is to code this on a Mac, fairly new with Macs; but I am ready to purchase a small utility that will accomplish those tasks ..
