I look at a facebook page of stuff. EG my wall. I want to remove a post. How do I do this? I dunno, there's a menu for that post underneath it, so I look there. It's not there. I hover around there. It's still not there. I maximise the browser window, just in case some element got hidden in a resize. Maximising is slightly tricky on OSX, I don't just clicky the green button. With the window maximised I still can't find it. I have a look around the post for extra items. I can't see anything. I start moving my pointer, and I see a flash of pale blue on a white background. Maybe that's it? Nope, that's some other function, but now I know there might be a hidden button. (Note that I don't know there is a hidden button, just that there might be one somewhere.) Eventually, I find this hidden button, and clicky, and the post is removed.

Can you imagine how frustrating that is?

Now imagine I'm someone who is used to using the keyboard; or I have a motor-function illness which means I find using mice hard or etc etc.

For sure I understand all the points about why some people love this functionality. But please give me an option to turn it off and have all controls exposed on the page.
