Slight topic drift - but related.
When your fingers automatically do certain things after a certain
pattern it's basically an autonomic reflex. It's one finger
following another why players of musical instruments repeat hard
passages until they get them correct. After enough practice they
don't have to work at the fingering - such as in a very complex
keyboard piece - as the finger have been trained to do certain
You've probably noticed this if you are a fast touch typist when
you go to type a word you don't use often but it starts with the
same pattern as a word you quite often.
That's part of being a human :-)
