I switch monitors really often: At work I have a very poor computer, and gpu too, which is bad at keeping its configuration, resolution and monitor position between each reboot. Both monitor are different size and resolution.

When doing that I often have applications that were on one of the monitors that remember their last position opened... so now they are unseen, at screen coordinates I cannot access.

I know there is a shortcut that can access the move functionnality of a window. Could you remind it to me.

Do you have other trick to center all opened windows into the visible screens ?
