You can make Vim scroll the text using the shifted up/down arrows, sort of like your browser (except with shifted keys :), by mapping Shift-Up to Ctrl-Y and Shift-Down to Ctrl-E.

<pre>
map &lt;s-Down> <C-E>
map &lt;s-Up> <C-Y>
</pre>

Shift-Down will then scroll down (like moving a scroll-bar down, or like moving a cursor at the bottom of a window down), and Shift-Up will then scroll up (like moving a scroll-bar up, etc).

If you'd rather think about the text moving down/up instead of the cursor moving up/down, you can of course swap the mappings.

If you normally use j and k for cursor movement, and rarely use the arrow keys, you can map the arrow keys directly, in which case I'd probably map the shifted arrow keys back to cursor movement:
<pre>
map <Down> <c-e>
map <Up> <c-y>
map &lt;s-down> j
map &lt;s-up> k
</pre>

Vim by default maps s-Down and s-Up to Ctrl-F and Ctrl-B, for both normal and visual mode. Keep this in mind if you change some of the above mappings to "nmap", because you'll probably also want to look in to "vmap".

==Comments==
This would be great, but doesn't work with my combination of secure F SSH (windows) and TERM=xterm. The arrows cannot be mapped as <Up>, etc, nor the <home> key. Any idea about why?
