To edit a rule, either general or totalistic, one may move the cursor and insert values for the cell above the cursor. Some programs have a more elaborate cursor, with tabs, wraparound, and the possibility of flagging values which will not be altered by using the random rule generator x ( X overrides the flags). Again these features are experimental, and may possibly be confirmed in future versions of the programs. Later on the special commands which apply to are shown.
