See, * GNOME Files binds buttons 8/9 to back/forward: <a href="https://github.com/GNOME/nautilus/blob/master/src/nautilus-window.c#L74">https://github.com/GNOME/nautilus/blob/master/src/nautilus-window.c#L74</a> * Firefox use[sd] 6/7 for horizontal scrolling (no longer supported; deprecated in favor of native wheel events) and 8/9 for back/forward: <a href="https://github.com/mozilla/gecko-dev/commit/8c7fedbebdf7a8d10085ae7284dce334f1d019a8">https://github.com/mozilla/gecko-dev/commit/8c7fedbebdf7a8d10085ae7284dce334f1d019a8</a> * Here, Olivier Crête states: "I'm attaching a simple patch that maps X mouse buttons 8-9 to the back/forward commands. The consensus amongst GTK+ and Qt seems to be that buttons 6-7 are for horizontal scrolling." <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=355477">https://bugzilla.mozilla.org/show_bug.cgi?id=355477</a> These all are seemingly codes from linux/input-event-codes.h taken relative to BUTTON_BASE, which is BTN_LEFT - 1 (<a href="https://github.com/GNOME/gtk/blob/master/gdk/wayland/gdkdevice-wayland.c#L47">https://github.com/GNOME/gtk/blob/master/gdk/wayland/gdkdevice-wayland.c#L47</a>) and plus 4 (<a href="https://github.com/GNOME/gtk/blob/master/gdk/wayland/gdkdevice-wayland.c#L1618">https://github.com/GNOME/gtk/blob/master/gdk/wayland/gdkdevice-wayland.c#L1618</a>, mentioning "old 4-7 scroll ones"). This leaves us with the following: * BTN_SIDE is button 8, used for the "back" command * BTN_EXTRA is button 9, used for the "forward" command * BTN_FORWARD is button 10 (or 6 without +4), should mean scrolling left * BTN_BACK is button 11 (or 7 without +4), should mean scrolling right Have you actually tested other mice with extra buttons & wheels? How do they behave?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
