It doesn't work. "KeyCodeList" could not be defined automatically. I
try to add a type definition to make it works, is it ok?
{ 'enum': 'Keycode',
'data': [ 'shift', 'shift_r', 'alt', 'alt_r', 'altgr', 'altgr_r',
......
'lf', 'help', 'meta_l', 'meta_r', 'compose' ] }
{ 'type': 'KeyCodes',
'data': { 'name', 'Keycode' } }
{ 'command': 'sendkey',
'data': { 'keys': ['KeyCodes'], '*hold-time': 'int' } }
New problems: special character '<' could not be added to enum, other
characters are fine.
