I am not sure we are talking about the same: If I click somewhere on  
a page and then shift-click anywhere else, above or below, everything  
in-between is selected no matter what. Why should it be any different  
if the two clicks are so far apart that you can only see them in a  
split window. The way I see it, you scroll the upper pane until you  
have the begin of what you want to select. You click it. Then you  
scroll the bottom pane until you see the end of what you want to  
select. You shift-click it.

But I am sure it is more complicated than what I think!

Particularly when both the human user and the machine being used are  
old. But the worst is that when you see the bottom you don't see the

Last time I took a look at emacs, I almost got a heart attack. I sure  
got a headache, though. Fortunately, I don't do such massive moving  
that often that I can't stick with TeXShop.
