Do you need this?

Yes, as VKEY is defined in keyboard_codes.h.

 namespace ui {
 
 // This table maps a DomCode to a printable character, assuming US layout.
 // It is used by DomCodeToUsLayoutMeaning(), which provides a fallback
 // interpretation when there is no other way to map a physical key.
 const struct PrintableCodeEntry {
   DomCode dom_code;
   base::char16 character[2];  // normal, shift
 } kPrintableCodeMap[] = {
     {DomCode::KEY_A, {'a', 'A'}},
