Dogs act like toddlers when you need help - but cats just watch. Scientists compared 3 groups: pet dogs, cats, and human toddlers in an experiment where a human parent hides and pretends to look for an object. 75% of dogs and children helped. Cats only helped if it was in their personal interest.

I remember wondering if something like the Goldtouch Elite Adjustable existed when I first started testing ergonomic keyboards. It didn’t at the time, as far as I could tell, but now a connected yet adjustable split board is indeed a product you can buy. It’s a solidly-built board and the ball joint connecting the two halves feels like it will put up with a lot of use. A squeeze of the lever at the top of the keys lets you set the board just how you like, adjusting both the vertical tenting and the angle between the two halves. There’s no programming to speak of, just the ability to swap a few function keys like print screen and home.
