All the alphabetic, number and symbol keys are placed on the back side of the keyboard that are off sight of the operator, The positions of the keys are illustrated by print of key indicia in the front side of the keyboard so the operator can locate the keys. The layout of the keys is suitable for touch typing from the back side but still keeps most of the fingering of QWERTY layout. The F1 to F12 keys, arrow keys and page control keys are placed on the upper part of the front side of keyboard to be operated by thumbs. The ‘Space’, ‘Backspace,’ ‘Return’, ‘Shift’, ‘Ctrl’, ‘Alt’, ‘Caps lock’, ‘Tab’, ‘Fn’, ‘Esc’ and ‘Delete’ keys can be allocated onto four predefined key zones on the keyboard surface in different arrays and combinations.
