The finger position stickers feature color-coded stickers that show the typing student which fingers to use with each key. The stickers also show the upper and lower case character for each key for the beginning student. The Finger Position stickers are perfect for the beginning typing student to graphically show them the "typing zones" for each finger. After the student has mastered the basic typing skills, the black, opaque typing mask can be used to test the student's ability and to teach them to type without looking at the keyboard (Lexan Polycarbonate Material, 3M Adhesive) .
