We ran into a gentleman that had no clue about these commands. When he wanted to keep or send a particular part of something on a website, he would shrink his browser to half size, open an instance of notepad and then type the text verbatim and then save it. He had an entire library of folders, based on subject and date, filled with text files of things he had copied over time .
Keep in mind, the gentleman did not touch type…it was index fingers and cramped wrists for his efforts.
I swear, when he finally grasped the concept of copy and paste, I thought the Hallelujah Chorus was going to fill the room.
