Key Binding Issues
 

I've been trying to get space+q/w/e/r to result in leveling up each ability. I edit and save the input folder to have:

evtLevelSpell1=[Space][q]
evtLevelSpell2=[Space][w]
evtLevelSpell3=[Space][e]
evtLevelSpell4=[Space][r]

However when I go in game just pressing q/w/e/r will level up (and use) the ability. What am I doing wrong? Is there any way to bind space+q/w/e/r to level up?
