Some scrollbars include a visual position indicator to help determine where the scrolling action has gone or will go to in the content. For multipage content, an indicator of the current page number vs the total page number can be included next to the thumb as scrolling occurs, and wider scrollbars can include an overview of the entire page. In scrollbars like those used in phone contact lists made up of the letters of the alphabet, the letter corresponding to the current area can be displayed larger or highlighted in some way. While these are stable and provided by the application, some applications and search engines allow for the use of relevance markers provided or added by the user. These can be strictly visual or can automatically stop action within the scrollbar once each marker is reached. These can be emphasized with color or even sound to further assist the user in finding what they need within the content.
