Additional thing I noticed this morning, I'm getting much more comfortable with the arrow keys. For TE owners: try this (in whichever hand is your dominant), but the example is for the right (dexter) hand
- Place the thumb on the Down arrow
- Place the 1st (pointer) finger on the left arrow
- Place the middle (baddie) finger on the up arrow
- Place the finger next to the pinky on the left arrow
May be an obvious point, but with a small hand shift to the lower right (for the right hand) you can use all four fingers for navigating including the thumb. Faster and better ergonomically as it spreads the work around to four fingers, and you don't have one finger doing double duty, as for the typical non-star arrow key block configuration.
Pretty neat, I'm practicing with it and it's a very natural and fast hand shift and thumb tuck to get this position.
