I wanted to use space bar as my Alt Modifier, which is what I'm used to in another MOBA
As there's no option for that (PS: Please add it), I tried using space bar as my CTRL modifier (space bar now is -> CTRL)
I replaced Alt with CTRL, in all Alt controls (such as self-casts and pings) [Alt now is -> CTRL, which is space bar]
Once I applied the changes, I went in-game to try them out, but they didn't work:
1. Even though CTRL wasn't my modifier anymore, if I for example tried to Space Bar+Q to level up my ability it wouldn't work.
