I activate the option which permit to windows under the cursor to have the focus. To raise the window, I need to click in it. But, there is no differences between a scroll-up/scroll-down and a click. Is it a bug?
This is very usefull when we don't want to raise the web browser to navigate in the current page whereas we have many other documents opened in raised windows.
window manager tweak, select accessibility, unselect raise with any button
