-Note that you have to put the actual control characters in the
-configuration file, not a '^' followed by a character. To do so with
-Emacs for instance, you have to use the C-q key followed by another
-key: C-q C-a inserts "^A", C-q C-[ inserts "^[", etc.
+Note that depending on the configuration of your system, the sequence
+associated to the M-r key, which is here "C-[r", may differ. To figure
+it out, simply press C-q followed by M-r in the console.
