When I have to use a Windows machine for long periods of time, it hurts my fingers.
Why? Look at your keyboard. Put your left thumb on the Ctrl key, and your left index finger on the W key, now on the C key, and then on the V key. Now try it again, but put your thumb on the Alt key (or Command key, for use Mac users.)
Which is more natural? putting my thumb on the Command key on my Mac feels natural. I am not stretching and crossing my fingers over to hit the target keys. Using Windows, my thumb has to go way to the left, underneath my index finger.
Is it just me, or does the same thing happen to you?
