Smart. I was confused because in treeview I thought that S-SPC scrolls 
the other direction than SPC. In fact it doesn't, it's just than on my 
long articles (which occupy twice the length of a window) doing SPC (or 
S-SPC which is the same for me) at the end of the news, wraps back to 
the top. Instead, in plain view it doesn't wrap to the top but says end 
of buffer. Maybe we should make SPC behave the same in treeview and 
plainview?
