Offline Paradoxes

I don't often write with a fountain pen ... And once again I find myself on the fact that when in a handwritten (!) Russian text you need to write something in Latin, the brain automatically slows down, mentally preparing to press "Ctrl + Shift". And experiencing an incredible relief from the fact that they do not need to press ...
However, it is terribly frustrating that there is no “Del” button on paper, and there are no operations with a buffer. But not as much as the lack of “Ctrl + F” in paper books.
I also noticed that I am very wary of devices that do not require some time to turn on and off (load and save parameters) (although there are not so many of them - except for a hairdryer, nothing has occurred). Some kind of wrong devices.
UPD : Well, after all the truth - in the Russian text to write in Latin and to feel some kind of small joy that you are still a person, and you do not need the controller key - this is really great!
