    New dired commands to navigate symbolic links
    
    Like dired-prev-dirline and dired-next-dirline
    but for symbolic links.
    
    * lisp/dired.el (dired-prev-symlinkline, dired-next-symlinkline):
    New commands.
    (dired-mode-map): Bind them to '{' and '}'.  Add menu entries for them.
    
    * doc/emacs/dired.texi (Dired Navigation): Document them.
    
    * etc/NEWS (Changes in Specialized Modes and Packages in Emacs 28.1):
    Announce them.
