This command shows a status window with icons that help tracking the mouse position as seen by the target program after the coordinate scaling transformations:

The icons will show in a window space that corresponds to the virtual desktop resolution. There are 4 types of icons, each one referring to a specific mouse transformation:

| blue viewfinder: mouse coordinates received by the Windows message processing routine as defined by USER32 SetWindowLong(GWL_WNDPROC) system call.
| yellow viewfinder: mouse coordinates received by the Windows hook callbacks defined by USER32 SetWindowsHookEx system call.
| green viewfinder: mouse coordinates of the POINT pt field of Windows messages extracted from the message queue with USER32 PeekMessage / GetMessage calls.
| red viewfinder: mouse coordinates returned by the USER32 GetCursorPosition system call
