I have found 5 or more tools for typing by doing searches. Typing Master is 1 I use because it has a typing meter that tracks typing in real time, then a practice mode to work on problematic letters and words. There's a paid version but I have found 1 or 2 that are free or that have some advertisements with it. I use Typing Master 5 because I, like here, can copy and paste text into it to make a lesson to work on. It takes some reading, experimenting and using to learn how to add a lesson.
