Smart Mouse can display special pointers to indicate that constraints are met. You can toggle the pointer display if more than one con- straint is active. The Pointer option (see “Constraint settings,” next) must be active to see Smart Mouse pointers. To toggle the Smart Mouse pointer:  Press Command (Mac) or Alt (Windows) when a constraint pointer is visible. If another pointer appears, both constraints are met. The symbols won’t change for different settings of one constraint type, such as two different val- ues for the Angle constraint. Customizing Smart Mouse constraints You can activate constraints, change their values, and add and delete constraints in the Smart Mouse Manager. 1 Choose Smart Mouse in the Layout menu to open the Smart Mouse palette if necessary, then double-click a constraint icon to open the Smart Mouse Manager. 2 To activate or deactivate a constraint, click to the left of the constraint name in the scrolling list. You can activate multiple con- straints, but only two can affect the pointer at once. 3 Configure the constraint settings described next and click OK. Constraint settings The settings in the Current Constraints area at the top of the Smart Mouse Manager affect the behavior of all Smart Mouse constraints. Select a constraint in the list to see its symbol in the Icon box. Priority When multiple constraints are active, those at the top of the scrolling list take precedence over those lower in the list. To change the priority of a constraint, drag it to a new position in the list. Source Lines If checked, Canvas displays a line to show that the pointer, or an object you are moving, is aligned horizontally or verti- cally with a snap point — such as the corner of an object. Pointers If checked, constraint symbols appear as you draw or drag objects to indicate that a constraint is met. Constraint Range The maximum distance, horizontally or verti- cally, from a target point at which the constraint causes the pointer to snap to the target point. Objects Within For absolute constraints only, specifies how close the pointer must be to an object for the object to trigger the constraint. Tip To temporarily hide Smart Mouse pointers, press the Shift key. Smart Mouse pointers reappear when you release the Shift key. Constraints are listed at the top of the Smart Mouse dialog box, from High to Low priority. A check mark indicates active constraints. Constraints preceded by a delta symbol (    ) are relative constraints.
