[links] Customizing links (input help)

[Yan Seiner]

I need a bit of guidance.

We're currently using a javascript frontend which takes keystrokes 
coming from a keypad and changes the values in a form.

For example, the letter 'a' results in a numerical field being 
incremented by 1.

I've looked at the code in links, and I think I can modify it to do what 
we need, but I need a bit of help with the input routines.

I can't quite figure out how the keystrokes get into links, and more 
importantly, where in links do they go to update a form field.

I have the other stuff figured out, but the 'field editor' is the part I 
am missing....
