I have ignored this issue for a while, but i figure it's about time I look for an answer to it.
For jumping, I prefer to use mousewheeldown, though it does not let me assign jump, or any other movement control to it.
I have removed all other controls that involved the mouse by default, but it still does not assign.
In the control categories that involved mousewheeldown, i was able to assign it with proper functions.\
If anyone knows a fix/workaround to this issue, please let me know.
