## .kl file format

A .kl file is a binary file format which stores, for each ascii code point in order from *ASCII(0)* to *ASCII(127)*, a 16 bit little endian value composed of a *USB HID code* in the low order byte and a *bit set of modifier keys* in the high order byte. 

*USB HID codes* for each key of a standard 102/105 key keyboard are (as displayed passing option `-k` to the software):

         ---------------------------------------------------------------------- 

*Modifier key bits* are, in order starting from bit 1: *lctrl*, *lshift*, *lalt*, *lgui*, *rctrl*, *rshift*, *ralt*, *rgui*.
