A rule’s position in the listing of rules in the Rules panel is important because of the rule evaluation procedure described in About rule evaluation. Rules are always added to the rule queue in the top-to-bottom order shown in the Rules panel.
You can change a rule’s position by selecting it, and then using the and icons on the Rules panel toolbar to move the rule upwards or downwards, respectively. You can use the Ctrl and Shift keys to select multiple rules at the same time and move them as a group.
The icons are only available when a rule is selected and their function is available for that rule. For example, you cannot move the first rule further upwards.
