Alignment Toolbar
By default, the Alignment toolbar contains tool for controlling the alignment of markups in a document. All the buttons on the Alignment toolbar will be grayed out if no markups are selected. The buttons on the toolbar become active depending on the number and type of markups that have been selected. If an alignment tool is not active, that means it cannot be used on the selected element or elements. See Aligning Markups for more information.
