Use Invisible Elements preferences to show or hide markers that represent elements such as scripts, comments, and named anchors that are not visible in the Document window. Showing invisible elements lets you select and view them and change their properties in the Property inspector.
To change these preferences, choose Edit > Preferences, click Invisible Elements, and then choose elements to make visible or invisible. A check mark next to the name of the element in the dialog box means the element is visible. View > Invisible Elements must be selected for the markers representing invisible elements to appear in the Document window.
