Guys, I think the question isn't about switching back to the previous webpage, but going back to a particular spot on a single webpage when you lose your place.
I don't know of any keyboard shortcut to do that and really doubt there is one when you use the Home key. You would have to mark your place and I don't see how to, cause when you move away from your place using the keyboard you move the caret and it doesn't have any way to remember where it's been before that it needs to go back to.
Plus this is what the scroll bar is for. It doesn't mark your place, but if you grab the bar with your mouse you can get back to where you were before pretty quickly. However, I too can get frustrated when reading a long article of mostly plain text, if I go up or down a few paragraphs it can be hard to find your previous spot. Sometimes I will highlight some of the text before I move away from it--I find that helps me find my way back to it--but I don't always remember to do that. Also, with this method you have to use the scroll bar, otherwise you'll lose your highligting mark.
