A single elevated case shift key is located on the left hand end of the lower letter key row. The elevated stroking surface of the carriage return key is located at the right hand ends of the lower letter key row and the home key row. Steeply inclined key tops slope down toward neighboring home keys to guide fingers to the proper home position and to facilitate actuating non-home keys.
