-    # 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.
