> It’s sort of obvious to figure out that the less we have to move our hand from the home row to the arrow keys, the more time we save. There is however a more formalized way to look at this in the field of user interface design. I feel like this thinking is flawed. When you are pressing a sequence of keys, your fingers don’t wait for the first key to be pressed before the next finger starts moving to its key. This means that it is in position right after the first key is hit. One of the reasons that more optimized layouts (Dvorak, etc) don’t seem to produce any speed up, Even though from a Fitt’s law perspective they should. Having a tiny keyboard will not make you faster and may slow you down because of all the layers you now need to use.
