If no objects are selected when you press the Opacity icon, the Opac- ity slider isn’t available. The Opacity icon in the toolbox displays an opacity scale. When an object is selected, a line in the scale indicates the object’s opacity set- ting. The left end of the scale represents 1% opacity and the right end represents 100% opacity. In the Transparency palette you can adjust the opacity of a single selected object. To set a selected object’s opacity, drag the Opacity slider or enter a percentage from 1% to 100% in the text box. The Transparency palette also lets you specify the scope of an object’s opacity setting. See “Controlling the scope of transparency effects,” next, and “Using the Transparency palette” on page 20.355. Setting opacity for multiple objects You can use the Opacity slider in the toolbox to set the opacity for more than one object. In contrast, the Opacity slider in the Transpar- ency palette is not available when more than one object is selected. Using the Opacity slider in the toolbox when multiple objects are selected will apply the same opacity setting to each selected object. To adjust the opacity of a group object, you can use the Opacity slider in the toolbox or in the Transparency palette, because a selected group object is considered one object. Opacity applies to a group object as if it were a single object. This is different than changing the opacity of multiple selected objects that aren’t grouped. Drag the Opacity slider to set the opacity of selected objects Tip You can set opacity quickly by Tab-clicking the opacity scale in the toolbox. A line in the scale shows the setting. Click the middle of the scale to set opaci- ty to about 50%.
