The invention embodies touch identification techniques to aid in recognizing computer keyboard keys. This method of key signing will reduce normal typing time for keyboarders by eliminating the need for visual confirmation of hard to reach keys or troublesome keys. According to the invention, the keys are identified using touch sensitive attributes. These include a difference in texture, elevation, material, or temperature, a vibration sensor, a plurality or combination of these, and any other method that alters keyboard key properties for the purpose of touch recognition. The identifier must have a contrast of physical properties significant enough such that the key can be recognized without looking.
