But I thought they lack jumping forward and I decided to start my first emacs lisp code as follows. (I mapped C-p, C-o, C-l to the functions) I think this code is really ugly and any comments are welcome. And can anyone please advice me how to make 'push-place-uniq' automatically called every time when I execute some kind of jump actions like searching texts, opening a file or searching tags etc?
