Which fingers to press the system keys and their combinations?

Question

Keyboard

I learned touch typing pretty quickly, but as a programmer, I have to press the system keys and their combinations almost more often.
And here is a big problem - typing simulators usually do not teach this, these keys themselves are always located very differently in different keyboards and I handle them very awkwardly and looking at the keyboard.
Maybe someone knows what interesting materials on this topic to study? Interested in such keys as F1-F12, ctrl, alt, cmd, fn and their combinations with others.

Answer 1

Everyone urinates how they want.
I press Ctrl and Shift with my little finger, Alt and Cmd with my thumb.

Answer 2

in Windows, I changed contr and alt in places in the system settings in order to press the contl with your thumb (that is, now alt, by analogy with cmd in poppy).

Answer 3

1. Depends on the habit.
2. Depends on the size of the hands, the size of the keyboard and the location of the special keys on the keyboard.
