Well, actually, they could have been looking at scanned copies of the relevant documents, rather than simple computer data text.
Quite so. Although we should remember that TOS never showed us a text-input keyboard, neither QWERTY nor any other sort that would have had all the letters of the alphabet as separate keys. On the other hand, we do see a text-input method that relies on a stylus and a pad. Perhaps inputting text with keyboards is out of fashion, and the standard method is a pen-like device again, resulting in "handwritten" documents.
