CP-Link 3 Shell Extension
The CP-Link 3 Shell Extension extends the desktop context menu. The additional context menu entry makes it possible
to move windows that are displayed on another desktop, and which therefore are not visible, onto your own desktop.
The Desktop context menu is opened by right clicking the desktop:
If the mouse is pulled to the CP-Link 3 entry, a window opens showing a list of all the open windows currently displayed
on the host computer.
If one particular window is now selected by clicking the mouse, it will be moved onto the desktop from which the desktop
context menu was called.
