# Keystrokes of GNU Readline will timeout it with the specification of
# "keyseq-timeout" when waiting for the 2nd character after the 1st one.
# If the 2nd character comes after 1st ESC without timeout it has a
# meta-property of meta-key to discriminate modified key with meta-key
# from multibyte characters that come with 8th bit on.
# GNU Readline waits for "keyseq-timeout" milliseconds to see if the ESC
# is followed by a character, and times out and treats it as a standalone
# ESC if the second character does not arrive. If the second character
# comes before timed out, it is treated as a modifier key with the
# meta-property of meta-key, so that it can be distinguished from
# multibyte characters with the 8th bit turned on.

# GNU Readline will wait for the 2nd character with "keyseq-timeout"
# milli-seconds but wait forever after 3rd characters.
