G-code lines can be bookmarked. Bookmarks are set by selection of the G-code line where the bookmark is required and use of the Toggle item or press of the shortcut key. Multiple lines can be bookmarked. When a line has been bookmarked it highlights.
Selection of a Bookmark and press of the Toogle item will clear it. Alternatively all Bookmarks can be cleared at once using Clear. When bookmarks are cleared highlight are removed.
