Copying a grid differs from moving a grid (or any other object) only at
the point that copying does not delete the initial object (grid) from its
origin coordinates, but duplicates the grid (or any other object) in the
new coordinates specified by the user.
The algorithm for copying a grid is as follows:
Make sure all operations are canceled or press the ESC key.
Select the required grid.
Enable the Ctrl+C hotkey combination.
Indicate the 1st point defining from where to copy the grid.
Indicate the 2nd point defining where to copy the grid.
Press the Esc key to cancel the copying operation.
