When you want to add a new page to your InDesign document, Command + Shift + P is the quickest way to do it. The keyboard shortcut will add one new page after the currently selected page in your document. Another way is to Option + Click on the New Page button in the Pages palette, which will open the Insert Pages dialog box. This method will allow you to specify the number of pages to insert and where to insert them, as well as what Master page to use.
