Within a TreePad data file there may be one or more key nodes to which you keep returning frequently. You can create a bookmark to each one of them in the Bookmarks pane to enable you to jump quickly to any of them.
Another use for bookmarks can be to mark unfinished articles you have been editing in order to find them again quickly when you reopen your file.
Where bookmarks are stored
Bookmarks, and the order in which they are listed, are stored inside the current TreePad data (.tpd) file.
