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.
