Keyboard layout

Replace CapsLock with Esc

US-Mac keyboard layout under linux has the following keys with Alt Gr down:

\` ¡  ™  £  ¢  ∞  §  ¶  •  ª  º  –  ≠
    œ  ∑ \´  ®  †  ¥ \¨ \^  ø  π  “  ‘
     å  ß  ∂  ƒ  © \˙  ∆ \°  ¬  …  æ  «
   §  Ω  ≈  ç  √  ∫ \~  µ  ≤  ≥  ÷

\ ̛ ⁄  €  ‹  ›  fi  fl  ‡  °  ·  ‚  —  ±
    Œ  „ \´  ‰ \ˇ  ¼ \¨ \ˆ  Ø  ∏  ”  ’
     Å \/  ð \ ̉ \˝ \ ̣  ½    Þ  þ  Æ  »
   ± \¸ \˛  Ç  ◊  ı  ˜  ¾ \¯ \˘  ¿ 

(symbols prepended with \ means that they can modify another letter)
