The Bookmark files are documents that resides on your local machine and you are able to edit and change. The append feature, invoked by pressing an 'a' while viewing a document will add the current document or the currently highlighted link to your default Bookmark file, or to one you select if multiple bookmarks are enabled. The remove feature, invoked by pressing an 'r' when a Bookmark file is being displayed, will remove the currently highlighted link. You may set and modify the paths and names of your Bookmark files and enable or disable multiple bookmarks in the Options Menu.
