Abstract
Abstract A keyboard training aid has a support resting on the keyboard around the text entry keys and an opaque cover pivotally mounted on the support. The cover extends over the text input keys so that they cannot be seen by a training operator. Two apertures in the top cover are aligned between the keyboard operator and the home keys in the center row so that the home keys can be viewed.
