If you’ve (oops) built a document with the incorrect page size or need to change margins, the world has not ended. InDesign’s Layout Adjustment can save your proverbial bacon. Choose Layout > Layout Adjustment (Figure 11.25), and then change the document size or margin settings. The default settings will do all the right things. Guides will move as will objects snapped to those guides. Text frames created by autoflowing text will expand or contract as necessary, adhering to shifting margins. Radical changes in page size or margin settings may require some massaging after the treatment, but you may be surprised by how good the initial results are.
