Sorry for raising a rather trivial point, but I am often frustrated by the fact that if you visit a page such as https://docs.sympy.org/latest/tutorial/manipulation.html, and try to select some of the code with a view to copy/pasting it, you are instantly moved to the SymPy Live Shell.
There is a button 'Hide SymPy Live Shell', but that just hides the shell once, as soon as you try again and select something from the tutorial. it reappears.
Have I failed to notice a way to stop this happening, so I can cut/paste directly where I intend?
