Abstract: Virtual bookmarks can be set in digital content to enable a user to quickly locate a portion of interest. A user can provide an input to enter into an overview mode wherein multiple pages of content are displayed concurrently. The user can navigate through the pages, and when a bookmarked page is caused to no longer appear on the display an overlay element such as a thumbnail of the page can be positioned near the edge of the display, representing the current relative location of the page in the overview. A user can select one of the displayed pages to view, or can select the bookmark overlay element to return to the current page. A user can perform an action to cause the bookmarked page to be updated, or can perform various actions to cause multiple bookmarks to be created with respect to the content.
