Step 4: Right-click and select "Paste Special" from the dialog box;
Step 5: From the "Past Speical" drop-down list, select "Paste Transposed";
Step 6: The contents are now in a new location with a new direction.
Alternatively, you can get the "Paste Transposed" command in the "Edit" tab from the ribbon.
