5 and 6 on numpad for left-right and 3 on normal keyboard for hyperdash. My shitty laptop and its even shittier keyboard sucks though and sometimes 5 or 6 blocks itself while playing so I'll probably have to change it soon (again, I had like 5 other combinations, just 3 for hyperdash is always there ).
I don't know why I chose to play like this primarily because Im right handed and I do movements in this game with left hand, I just got used to it and I tried rebinding but just sucked really badly
