I have a G502 and I wanna use the side buttons for strafing but I can't because the keyboard keybind for strafing is grayed out and the mouse keybind doesn't detect any other mouse inputs other than left, right click, and scroll wheel (because I have other special buttons on my mouse).

AFAIK you cant bind anything to that function, unless anyone knows a fix in the config or something. But its not needed for the unity port as you reach SR50 by just holding up and a left or right strafe key with auto run enabled so you don't have to hold shift all the time.

Oh, that's good to know because I have been trying to practice the jump to the exit switch on E1M4 and I can't get it consistently (I get it sometimes)

@jjjoe_ There are tutorials and such located under guides, and also an E1 tutorial with some helpful tips on nailing the E1M4 jump (see latest news for that tutorial)
