If I have 3 monitors, and would like a window to span two of those monitors, is there a shortcut to do this?

It's not a huge deal, but it would be nice to have a shortcut that might make the current window span the current monitor and the next monitor to the right or left... (And maybe a similar shortcut to move the window one monitor to the left or right?)

Not sure if anyone else would find this particularly useful, but I use Eclipse, and have found it to be helpful to have it setup with Eclipse spanning 2 same-size monitors, while email and browser are on the 3rd.
