completion command replaces that with the next completion alternative,
in a cyclic manner. If you give @code{completion-cycle-threshold} a
numeric value @var{n}, completion commands switch to this cycling
-behavior only when there are fewer than @var{n} alternatives.

probably be obvious which command is displayed for repetition. If you
type just @key{RET}, that repeats the command unchanged. You can also
change the command by editing the Lisp expression before you execute
-it. The repeated command is added to the front of the command history
+it. The executed command is added to the front of the command history
unless it is identical to the most recent item.
Once inside the minibuffer for @kbd{C-x @key{ESC} @key{ESC}}, you
can use the usual minibuffer history commands (@pxref{Minibuffer
History}) to move through the history list. After finding the desired
-previous command, you can edit its expression as usual and then repeat
+previous command, you can edit its expression as usual and then execute
it by typing @key{RET}.
