Abstract

Systems, methods, and computer-readable media that include computer-executable instructions stored thereon for displaying electronic documents keep track of portions of an electronic document that have appeared in a user interface window at some point in time (i.e., the portions that have been actually viewed by the user). These portions of the electronic document that have actually been viewed are designated the “viewable document section” of the electronic document. In some examples, scrolls bars and/or other electronic document view shifting elements become available to the user only if the electronic document includes a viewable document section that does not appear in the user interface window, and these scroll bars and/or other view shifting elements may be limited based on the content of the viewable document section (not the entire electronic document). If the user changes the user interface window to include portions of the electronic document that previously had not been in view, the viewable document section then changes to include this new, previously unseen portion. Accordingly, as the user inputs electronic ink or other information into the document, scroll bars or the like will not appear until the user takes steps to bring previously unseen ink or other information into view in the user interface window.
