-Set this variable to 0 to wait indefinitely for the next byte.  If you
-do this, you will not be able to use some keys that generate sequences
-that are initial subsequences of those generated by other keys; for
-example, @key{ESC}, @kbd{M-O} and @kbd{M-[}.
+If you set this variable to 0, it's unspecified whether a recognized
+byte sequence representing a key takes precedence over another
+recognized sequence representing a key that is an initial subsequence of
+the first sequence.  In some cases, you may be able to make pressing a
+special key on the keyboard that Info doesn't know about (for example, a
+function key) cause a command to be executed by setting this variable to
+0, and giving the byte sequence the key sends in @file{.infokey}.
