 Note how we cannot use =, SPC= to set a mark because that key sequence
 is already reserved as a special key sequence in =devil-special-keys=.
 In order to conveniently set a mark, Devil translates =, z= to =C-=
 too, so that we can type =, z SPC= and have Devil translate it to
 =C-SPC=.
 
-Also, note how the translation of =, m m= to =M-= allows us to enter a
-key sequence that begins with the =M-= modifier key.  Additionally,
-consider that =, [= is yet another way to type a key sequence that
-contains =M-= because =, [= translates to =C-[= and =C-[ <key>= is
-equivalent to =ESC <key>= which in turn is equivalent to =M-<key>=.
