All fast typing tutorials on the internet (image search) care only about keys that are below function keys. No one tells you what fingers to use to press those function keys.
Assuming you use all ten fingers and type without looking at the keyboard, what fingers are supposed to be used to press function (F1-F12) keys?
Is there an official typing method to handle functions keys?
If not, I understand that it is probably left for the personal preference. But if someone figured out that it is most optimal (on qwerty keyboard) to press f key with you left index finger and j with your right index finger, then there is a chance someone came up with the most optimal finger mapping for the function keys as well.
