is the same that's printed when you run 'cmds ls'. Note
that after each removal/addition, the index of the
commands change. So be careful when removing them after each
other.

You can also specify an optional parameter (index_end) so
you can remove all commands from 'index' to 'index_end',
including 'index_end'.`,
