Ancient history follows.
When I was in high school (late 1970s), my mom encouraged me to learn typing – on a prehistoric instrument called a Type-Writer – because my lefty handwriting was so atrocious. So I learned to touch-type early, but they didn't emphasize numbers & symbols in my typing class. Different typewriters had them in different places. Some I remember didn't have one or zero; we typed lower-case el and upper-case oh for those.
So anyway, my first job during college required a lot of numeric data entry on a Paleolithic computer whose keyboard didn't include a ten-key number pad. It did have all ten numbers on the top row. So I trained myself to touch-type all the numbers, by just sliding all eight fingers up & over from the home row. Over time I learned where all the shifted symbols on that row were, so I was able to touch-type everything except Escape, Tilde, Backquote, Brackets, Pipe, Backslash, ModKeys, & arrows.
Now everything is in reach. Thanks, WayTools!
