It's true: the indirect buffer shares its parent's text properties. But, the visibility cycling is applied only in the active window: either in the main buffer or in the indirect buffer but not in both windows at the same time. So, it works as expected to me. Thanks for the trick! But this trick seems like a workaround to meĀ : using visibility cycling in one window should not affect another window, isn't it? Thanks for your help. Francesco
