While I agree that it’s important for people to have an understanding of the values that the fediverse are founded upon, as well as associated etiquette, I still don’t think that the fediverse itself needs that much of an explanation for people to reach that understanding. Though platforms may provide tools that can be used for malice, a tool is only ever as good or bad as the intent of the person using them. I don’t think someone necessarily has to understand the technical aspects of the fediverse to know how to treat others. Maybe to put things in better perspective, like how much of a communal aspect there is to the efforts that maintain this network, but I think most people will get to that understanding on their own regardless if it’s truly in their intent. Inclusivity and kindness aren’t concepts that are unique to the fediverse, but human concepts that people learn, and unfortunately unlearn over entire lifetimes. And above all, I believe the best way to teach and convey values to one another will also always be the most intuitive: by example.
I only find it useful on laptop keyboards. I like the numpad for entering numbers, and I also like having dedicated keys for stuff like Home, End, and Insert when browsing or editing. It saves space when you can double the numpad for both.
