Comment 8 for bug 1738283

Note, os-autoinst is its own VNC client. Most of the implementation can be found in https://github.com/os-autoinst/os-autoinst/blob/master/consoles/VNC.pm . The functions relevant to sending key events are `shift_keys`, `init_x11_keymap`, `map_and_send_key`, and `_send_key_event`.
