my anecdata: when my family members complain about confusing things with computers the question "how do I know if there are more things down the page" is rarely the problem. By far the most frequent issue is "where did that file I just saved go?" followed by "how do I forward this and that together?" and "it doesn't work! I didn't do anything. Yes, it asked me something and I clicked something but I don't remember, but I didn't do anything"
