I'd like to scroll just one (active) pane when I press
Ctrl at the same time.
Example: first pane has a looong line, so that line is
not shown as fully and in second pane that line is
splitted to two lines, both lines fully visible. Now
it's hard to look at differences in line(s). If I
scroll first pane so that end of line is visible, begin
of lines in another pane are not visible.
Another example: two .ccp code files. One function is
moved enougth that they don't fit to view at the same
time. When I try to see difference in those functions I
have to scroll back and forth.
