Braille Keyboard Covers Keys

Use a drop of silicone to paste the individual covers over the keyboard keys.Under each cover is the corresponding symbol to make no mistake.The covers are slightly rounded to attach better in the recess of the keyboard keys. The Braille specifications were found here:http://www.brailleauthority.org/ueb/symbols_list.pdf Adding "SHIFT-KEY REMEMBER"For those symbols that are obtained with the SHIFT key, this additional element must be added between the key and the Braille key cover.This element increases the height of the Braille key cover by 3 mm (0.118 inch) and makes the blind person perceive a difference to the touch compared to the other buttons to remind him that he must also press the Shift button.
