Bookmarks serve the fast re-find of passages in the file or project.
FoldMaster supports local and global bookmarks, which can be set at any
text line. All bookmarks can be displayed and processed in a bookmark window.
They remain existing also, if a file is closed, since they are stored their
own file.
Beside the global bookmarks there can be used up to 10 temporary bookmarks
in each editor window, which are bound to the window.
The bookmark window provides the best possible overview over all bookmarks.
