S Strafe Left
E Forward
F Strafe Right
(this gives room for Q _ W _ A _ D _R _T _G to bind and easy to reach)
It looks cool but I haven't tried this yet. I still play W - A - D. Classic...
I strafe left and right with side mouse buttons, forward with both top mouse buttons held down. Turn with mouse, and I never backpedal. This leaves my left hand entirely free for abilities so never have to choose between moving and using an ability.
