Hey, lopansuperman here. Not so famous 1-handed keysmasher here. I play with specifically arrow keys by placing my thumb on the left key, my pointer finger on the down key, my middle finger on the up key, and my ring finger on the right key. This might be uncomfortable, but you'll get used to it. You don't need to use this and it might not be a good playstyle compared to the others, but at least it's one.

Happy fiffering.
