   Why bother with ESC-codes?  isn't 1B 26 xx long-winded boring?   
      
   my key-decoder can produce 256 single byte "almost normal ASCII"   
   within my Set1 (simple lookup translate):   
   20..7F as defined by ASCII and 80 for the EURO-sign   
   07,08,09,0F,0A,0D for ASCII-defined controls BELL,BS,TAB,BTAB,LF,CR   
   other 00..1F as CTRL @,A..Z,[|] (1B fore ESC-key)   
   81..8c for F1..F12   8d,8e,8f for num-lock caps-lock scroll-lock   
   90..99 all cursor keys   9a.9b,9c,9d for prtscrn,sysreq,pause,break   
   A0...Af all from the numblock (easy transform into Numbers by AND)   
   B1...BC ALT F1..F12   
   C1...CC CTL F1..F12   
   D0...D3 windoze keys   
   SHIFT ALT and CONTROL keys don't produce bytes, they just set flags.   
   and all not listed above got a special meaning in my OS.   
      
   my other LUTs can produce language specific bytes or game patterns.
