Using javascript to avoid the mouse and page scrolling

Here's the problem. It is not very easy to scroll a document when you're inside an input element. Arrow keys don't work, and Page Up/Page Down jump in big increments. What if you want to see just a few lines below the current element? Our clients hate to scroll. And they hate having to use the mouse. This just brings the two together.

FScroll is a JQuery plug-in which makes a page scroll to the currently focussed element, keeping it's position centered with respect to the document. This helps keep a bit of "context" around the currently focussed element - since it is centered, you can see a few elements both above and below the currently focussed element.

Here are the sources. And here's a page explaining it's usage in some detail. And oh, it does nested centering too. But it requires that the 'nesting' container have a css styling of position : relative (in the demo page, the div enclosing the table is positioned relative). This was not strictly necessary, but it made the coding a bit easier. If you can't live with the styling restriction, let me know. I'll try to do what I can.
