You can select objects according to their attributes (that is, properties) and their context within the page. The list of selected items appears in the Properties Editor window arranged by type and color.

With the special selection menu, you can:

• Select all objects with the same type, screen set, or calibration curve on the page. That is, select by context.
• Select an object, or all objects with the same type, color, or screen. That is, select by attribute.

In effect, you can group these selected objects and make screening changes to the group.
