• Special Key Codes

  In the code, I wanted e accent aigu, but you could use any of the codes you want, or add more buttons!

  Alt+0233 (é)
  Alt+0224 (à)
  Alt+0232 (è)
  Alt+0249 (ù)
  Alt+0226 (â)
  Alt+0234 (ê)
  Alt+0238 (î)
  Alt+0244 (ô)
  Alt+0251 (û)
  Alt+0235 (ë)
  Alt+0239 (ï)
  Alt+0252 (ü)
  Alt+0231 (ç)

  The magic is that you have to "press" and "release" the KEYPAD numbers after the ALT key has been pressed, then release all the keys, i.e.,

  # Press and hold the LEFT ALT
  kbd.press(Keycode.LEFT_ALT)
              
  # Press and release keypad 0
  kbd.press(Keycode.KEYPAD_ZERO)
  kbd.release(Keycode.KEYPAD_ZERO)
              
  # Press and release keypad 2
  kbd.press(Keycode.KEYPAD_TWO)
  kbd.release(Keycode.KEYPAD_TWO)
              
  # Press and release keypad 3
  kbd.press(Keycode.KEYPAD_THREE)
  kbd.release(Keycode.KEYPAD_THREE)
              
  # Press and release keypad 3
  kbd.press(Keycode.KEYPAD_THREE)
  kbd.release(Keycode.KEYPAD_THREE)
              
  # Release all keys
  kbd.release_all()
