However, to use the 10-finger system efficiently, it requires a lot of practice. I use to practice the free browser program "Type Fu" for the Google Chrome browser. There you can gradually learn to type words (in English). I am quite quickly ascended to levels because I already knew through the seminar Tippen360 where the keys are. Over time you will be getting faster, but I have to say that it is tedious because you have to always change. It's hard to get away from nunmal of many years of habit because one must not fool.
There should be no one to buy this software with the expectation "Then I can the 10-finger system perfectly," then you will not be disappointed. It is just a first step. Then you have to learn by practicing efficient use. It is not easy.
