I don't get it, you keep your hand on the mouse to reach the right side of the keyboard with your left hand(assuming you're right handed)? THAT would be awkward imo

What are you doing with your keyboard one-handed? I can't think of any real use for one hand on a keyboard aside from gaming and shortcuts like copy+paste. And this keyboard runs QMK so it's very easy to just remap any shortcuts that the split might make difficult.

I don’t use it one-handed. I use two hands and take one away when I need to use the mouse.
