Mouse button 4 and 5 in the webbrowser

In chose a mouse with 5 buttons in the preferences/input devices.
I use a Logitech mouse with 5 buttons and the wheel, of course.

Is it possible to give the buttons 4 and 5 useful functions like paging back or forward in the browser?

Yes It’s possible.
Nobody did it, so this does not get lost please open a ticket at
