Tipp10 is my go to. It's free and a portable version is available, too. The German version of Consumer Reports once compared it to a bunch of paid programs and it was better than any commercial software they tested.
It all comes down to practice. But you also have to practice correctly, so I would recommend either one of the typing exercice websites people here have posted, or Tipp10, which is a program that shows you text and also shows what finger to use for what letter when you are typing
Then it comes down to just focusing on using the right finger when you strike a key and then after a while it becomes automatic.
I honestly find it amazing you can type so fast without touchtyping!
I'm a lot slower than you with touchtyping (about 110 WPM in typing tests when I'm concentrating, although realistically my typical typing speed is probably closer to 90 WPM), but what I will say is that, speed aside, learning to touchtype has made me far more productive from just never needing to look at the keyboard. I can be reading a document, watching TV, getting real time feedback on my typing etc. which is really invaluable (more than I ever thought it would be).
Assuming you have to glance at your keyboard I'd highly recommend trying to learn - since you clearly already know where all the keys are it won't take you long. When I learnt I went from typing like you to touchtyping in ~2 weeks (some less-used symbols, aside), with 10 minutes practice most days in TIPP10 (I'm not saying it's the best free typing tutor, just the one I used which worked well for me) - just try to look at the keyboard as little as possible and concentrate on using correct fingers during those couple of weeks if you can.
Wenn du dich gegen einen Kurs entscheiden solltest, aber trotzdem Zehn-Finger-Tippen lernen willst, kann ich dieses kostenlose Programm empfehlen: https://www.tipp10.com/de/ Damit bin ich super klargekommen und konnte nach kurzer Zeit blind tippen.
Wanna learn how to type faster? I like this program a lot. It has a portable version so I can just throw it on a flash drive (that i carry everywhere) and practice anywhere. It has been quite a bit of help as I have been using it off and on during down time at work or school and my wpm have increased by like 10 in the span of 2 months(very little usage).
I think you might like tipp10, a typing program that does what you describe. It also supports some national layouts and using your own texts. I found it quite useful to learn to type code on the UK international layout which is for me the most practical layout as a programmer (one can just feed it some code and it selects the fragments where one makes most frequently errors).
P.S. Sound like I am promoting it? It is ad-free, free software (as in FLOSS) and you can get it for Linux (Debian/Ubuntu/Arch), as well as for Windows and MacOS.)
That's one of the things I really like about custom keyboards, you can customise them endlessly to your needs.
But did you go with ortho mainly because of the looks? I think that would be my reason. The clear geometric lines look even cleaner.
I am trying to type better too and found https://www.tipp10.com/en/ really useful to sort our my fingers.
Über den Informatik-Unterricht in der Schule brauchen wir nicht diskutieren, der ist unterirdisch hoch drei.
Umso wichtiger wäre ein fach Medienkompetenz, damit man diese absoluten Grundlagen aus dem Informatik-Unterricht auslagert. Würde im übrigen den Lehrern auch helfen, die davon wenig Ahnung haben und selber im #Neuland sind.
Dann könnte man im Informatik-Unterricht auch Informatik machen...
10 Finger tippen ist im übrigen herzlich unwesentlich für die ganze Sache. Ist für die Bedienung für Smartphones irrelevant, und selbst die meisten Leute, die in der IT arbeiten, beherrschen das nicht richtig. Man ist ja keine Tippse, sondern arbeitet hauptsächlich mit dem Kopf (nicht, dass 10-Finger schreiben nicht nützlich wäre, aber es zählt eher zu den Skills, die unter "ferner liefen" aufgeführt sind). Halte ih im Informatik-Unterricht deswegen auch für wenig angebracht, da gibt es wesentlich mehr andere Konzepte, die man lernen sollte. !0-finger schreiben kannst du mit der passenden Software völlig ohne Lehrer üben (ich empfehle https://www.tipp10.com/de/).
Took me a couple of weeks. If you've been typing long enough and have a rough idea of where the keys all are in relation to one another it really doesn't take long to train your fingers to touch type properly.
Honestly, teaching myself to touch type has been the single biggest time saver in my life and given how much time most people spend behind a keyboard it's a skill almost everyone should really invest time into.
Just use something like TIPP10, which is free, and practice for 10 minutes each day. Once you know the correct finger for each key you can also switch it up to something like Type Racer, which can actually be fairly fun. Not only will you quickly notice your typing speed shoot up, but not having to look at the keyboard ever leads to a whole host of additional productivity benefits.
Making the jump from 2-finger-typing to touch-typing will improve your productivity and likely make computer work "feel better" (more ergonomic, less strain, better flow). It will take a bit of determination because at first you'll be slower, and it will consume extra focus and concentration, but you'll see improvement quickly.
You can either use an online trainer (this one is great) or do what I did: draw or print a keyboard layout that shows which fingers do which keys, find a book you haven't read yet, prop it up, and then just type it up. Also touch-type your code to practice with symbols that aren't commonly used in normal text, if it doesn't affect your work negatively.
It's a lot like working out: tedious at first, benefits later. A good keyboard helps.
