|Thank you all. |
Perhaps I did not make myself clear enough. My fault.
I am talking about instance when I close, say, this page by mistake and end up on desktop with nothing open. ie No opportunity to use back arrows or any copy and save functions. Yes I could go through the start menu and retrieve but I was hoping there might be a simple undo function on the mouse that I had overlooked.
I shall just have to be more careful when closing sites when I mean to go back a page.
