[roundandround]

Sure typing speed utility drops off pretty quickly but if it is a bit lower or makes just a part of your brain stop coding and think about more physical matters that should be in muscle memory then I think it has an effect on your ability to write a flow of code. (I saw this a great deal with regional keyboard layouts.)

Its hard to say if what you program will ultimately be better or worse as being used to micro interruptions can mean more diligence as much as they can mean forgetting an important caveat. But generally I think it means you are progressing at a slower rate toward an integrated group of skills.

For editors and IDEs it can be quite similar for refactoring, debugging and analysis of the code base. The worse you are at using them or the more indirect your proximity to the exact code base of the version you are working with, the more you rely on building/maintaining mental models which has its benefits and dangers.

I think its very hard to say anything is right or wrong. I do think that the question of where you expect to be in terms of needing each skill as your mastery of others grows is the question.
