You can quickly duplicate a page in Adobe InDesign by Option-dragging the page icon in your Pages panel. If you want to duplicated page one and have it appear after page four, simply option-drag the page one icon until the cursor appears after page four, then drop it. This is much easier than dragging the chosen page icon down to the Create New Page button at the bottom of the Pages panel – espcially if you have that panel stretched vertically to accommodate a long document.
