scrolling down with a single click

Hello,
it has been a long time I have been thinking about my difficulty with 
scrolling - watching moving text. So I have been trying to find a way 
how to scroll to a certain position without the need for watching the 
moving content on the screen.

The basic idea is:

    -------------------------------------------------
    Before I start scrolling down, I usually know the
    top boundary of the area I want to make visible.
    -------------------------------------------------

Conventional scrolling is just an uncomfortable way of moving the area 
to the position where its top boundary matches the top border of the 
viewport.

My vision is that I do not need to scroll by moving something. Instead I 
just specify the top boundary of the area I want to make visible - and 
the computer scrolls for me! By specifying the boundary, I mean a single 
click on the imaginary top boundary of the area, probably with a 
modifier key pressed.

Example:

Image the following view of a file with a set of English words for 
numbers, followed by names of Greek alphabet characters. You can see the 
bottom part of the listing of English words and a beginning of the Greek 
alphabet. Imagine you want to see more of the Greek alphabet but you 
want to keep its top part visible.

| eighteen                              ^|
| nineteen                               |
| twenty                                 |
|                                        |
| delta          x                       |
| epsilon                                |
| zeta                                   |
| eta                                    |
| theta                                 v|
+----------------------------------------+

Using conventional scrolling, you would use the scrollbar or a mouse 
wheel and scroll as long as needed until word "delta" appears on the top 
of the viewport.

Using the suggested way of scrolling, you would just press Alt and click 
somewhere between the empty line and the line with word "delta".

I believe most people would not appreciate it. I consider it a 
significant improvement mostly for people with inferior eyesight.
