Dive not working with Jump action bound to a Mouse button.
I have been using MOUSE4 as Jump binding since 2.0.
Today I just unlocked Diving. The help popup mentioned to use CTRL+SPACE to dive, which works if you have Jump bound to SPACE.
However if you have it bound to MOUSE4 like me, CTRL+MOUSE4 do does perform a dive move, but just a simple jump.
A workaround for me is to set a secondary bind for Jump to SPACE. Of course it does not feel as natural since I don't use SPACE to jump.
EDIT: FIXED So please disregard this report.
