A couple of times I accidentally clicked something and on the desktop all the open windows were displayed side by side (as in Ubunt), but small. When clicking on any place, they returned to their original state.
This is NOT Win + Tab This is not one of these modes: http://windows.microsoft.com/en-US/windows7/Manage-multiple-windows
These are my windows, only greatly reduced and, as if dragged along a huge resolution desktop. How to achieve this?
