Speaking of, split boards break the keys into two separate parts you can position individually. You can put them shoulder distance apart, bring them closer together or angle them as much as feels comfortable. You can also put your mouse between the halves, which may feel like an easier trip for your cursor hand and could potentially help with conditions like repetitive strain injuries (RSI). Personally, I like being able to put my current snack between the two parts. I've also found that pairing a split keyboard with a good ergonomic mouse has helped me even more, particularly a vertical mouse.
A quadtree reduces this: rebuild the tree each frame, and for each object, query only the nearby region. Objects in distant quadrants are never compared.
