Reply to: Limitations of probing field-induced response with STM
Columnar or ortholinear keyboards stack the keys in orderly columns, often with rows that are not linear. Proponents claim this makes the keys easier to reach. Whether that’s true will be up to your fingers to decide, but I can say for certain that if you learned to type on a staggered keyboard, switching to a columnar layout is tough. It will take days, possibly weeks before you instinctively hit the C key. The N, M and B keys don’t fare much better.
