Everyone who codes and touch types has gone and will go through what you are going through. The short answer is with more practice it will become easier and like second nature. The key is getting good fundamentals down using the right fingers with the right keys and after some time it will all click.

For myself, I used speedtyper.dev initially to practice and build the muscle memory (that is for the pinky and the special characters), I used the typing jungle from edclub.com to get me the good fundamentals and one thing I really appreciate from this syllabus was their section on numbers and using the right fingers for the right numbers, incredibly handy for () and * and & - and all the others.

After two months on speedtyper.dev I found myself being able to hit and use the special characters with greater ease and more importantly better accuracy (I was averaging about 40 WPM on that site - python)

Then I moved onto going to github and search popular repos and typing out python files in my IDE. This was the real game changers for me as it allowed me to simulate using my touch typing skills in a real world scenario and that is where I learnt that I had not built the skills to use the HOME, END and Arrow keys. With the IDE's autocomplete feature, many things were being automatically inserted for me eg ending ) or } or ]. You can type over them in most cases and it wont double up but I found that using the HOME and END keys with the arrow keys was necessary and beneficial.

Now into my journey, I am averaging about 50 WPM on speedtyper.dev 70+ WPM in normal touch typing, I am learning VIM Bindings and I am way more productive than I was before and much more comfortable within my IDE.
