How do I install a keyboard overlay for languages that require one on the E57540c model?

Pull the keyboard out, then peel the paper backing from the overlay at a sharp angle so all labels adhere to the clear sheet. Align the top corners of the clear sheet to the corners of the Esc and Delete keys, support the keyboard from the bottom, firmly press the labels in place, and then peel the clear sheet off at a sharp angle.
