Most ergonomic keyboard layouts fall into two categories: unibody (or Alice) and split. The former is a single board with the two halves of the keys rotated about 30 degrees apart at the bottom. The separation forms an A-shaped space between the keys — which has nothing to do with why it’s called an Alice layout, it’s just a happy coincidence. This subtle tweak pushes your elbows away from your ribs while keeping a straight line from your forearm to your middle knuckle. Using one, I pretty instantly felt more open along the front side of my body. This layout more closely resembles a traditional keyboard, so it should be easier for most folks to get used to than a fully split option.
Another example: why do so many languages implicitly view the right hand as good (for instance, associating the direction right with the ethical concept of rightness) and the left hand as bad, maladroit, sinister?。一键获取谷歌浏览器下载对此有专业解读
