Missing ESC key code in USB HID_KEYBRD_Key table array

[Robmar]

The Escape key was mapped to 0x00 in the USB HID code, I added it and it works fine but I'm curious to know why it was absent?  Bug/oversight, another method used for Escape key detection?

#ifdef QWERTY_KEYBOARD
static  const  uint8_t  HID_KEYBRD_Key[] =
{
  '\0',  '`',  '1',  '2',  '3',  '4',  '5',  '6',
  '7',  '8',  '9',  '0',  '-',  '=',  '\0', '\r',
  '\t',  'q',  'w',  'e',  'r',  't',  'y',  'u',
  'i',  'o',  'p',  '[',  ']',  '\\',
  '\0',  'a',  's',  'd',  'f',  'g',  'h',  'j',
  'k',  'l',  ';',  '\'', '\0', '\n',
  '\0',  '\0', 'z',  'x',  'c',  'v',  'b',  'n',
  'm',  ',',  '.',  '/',  '\0', '\0',
  '\0',  '\0', '\0', ' ', '\0', '\0', '\0', '\0',
  '\0', '\0', '\0', '\0', '\0', '\0', '\0', '\0', '\0',
  '\0',  '\0', '\0', '\0', '\0', '\r', '\0', '\0',
  '\0', '\0', '\0', '\0', '\0', '\0',
  '\0',  '\0', '7',  '4',  '1',
  '\0',  '/',  '8',  '5',  '2',
  '0',   '*',  '9',  '6',  '3',
  '.',   '-',  '+',  '\0', '\n', '\0', '\e', '\0', '\0', '\0', '\0',	/* Modification - changed \0 to \e for Escape key detection */
  '\0',  '\0', '\0', '\0', '\0', '\0', '\0', '\0', '\0', '\0', '\0',
  '\0', '\0', '\0', '\0'
};

Hi @Robmar 

We can confirm HOST MW for HID class will be updated.
