outl-mouse that used
outline-minor-mode plus a few pixmaps and mouse keybindings to let old lazy guys to hide and show (in my use case) sections and subsections etc of my AUCTeX buffers, etc etc.
As I have googled for a while
C-h a out.*mouse
</edit> but I haven't found anything relevant, here I am asking if you know of an Emacs' package to that effect.
