It is possible to copy and paste rules within the same logicsheet and between different logicsheets. To copy a rule, right click on the rule and select the Copy Rule option. To paste a rule from the clipboard right click on a rule (or the rules container) and select the Paste Rule option. The pasted rule will maintain its original priority, which will be used to position it within the rules already present.
This feature can be used to copy rules within a particular RuleBase, but more usefully, across different logicsheets, even if they are in different projects.
If you wish to copy a condition or action rather than copying a whole rule, you can simply click and drag the source component to where you would like the copy to be placed while holding down the Ctrl key on the keyboard. If the Ctrl key is not pressed, then the action or condition will be moved instead of copied.
