Hey, I just saw you commented on the Mothergunship patchnotes regarding binding scroll down to jump. I know a way to do that - a program called Autohotkey (#notasponsor). I've used it for years for rebinding keys or even more complex stuff.
The only downside is that it rebinds scroll down to space, so you can't scroll down in lists anymore. You could use another key to toggle hotkeys temporarily. Just add a suspend command at the beginning of the script, so the entire script would look like this:

F1::suspend ;this is a global hotkey, so use whatever else you want
return

#IfWinActive , ahk_class UnrealWindow ; MOTHERGUNSHIP
WheelDown::
SendInput, {Space Down}
Sleep, 50
SendInput, {Space Up}
return

Just install Autohotkey, right click on your desktop - create new script, rename it however you want, right click - edit and paste the code above. Save and run the script. Voila.
