Self-Cancelling Rules & Actions |
|
By setting an action or rule to nothing as the last of a set of chained tasks, it can be self-cancelling. This can be done as part of the rule/action itself. Consider this rule:
Color=blue;Rule="";
When the rule is run, the note's Color is set to 'blue' and the Rule is set to nothing. Thus the Color assignment is run once-only before the rule ceases to exist.
