I am programming since a looong time, but I somehow never learned to touch-type. In 2020, my org then had mandatory home office and I used a nice FLOSS program called "TIPP10" to learn it - 15 minutes every morning.

It is certainly a little distraction less, no question. But typing speed is not programming speed. The most time spent is wondering what the requirements should say, thinking about how to make something work, or wondering what a piece of code one needs to use is supposed to do. And only after that comes inquiring with people what they were meaning or thinking.
