Check out the clickCharChunk function.

Use the formattedHeight function to determine how far down you need to go.
You can ask for the formattedHeight of a chunk of text, e.g.:
the formattedHeight of line 1 to 60 of fld 1
Note that selecting the text by script will also scroll the field. (If you
have any trouble putting together a script that scrolls exactly as you want
with formattedHeight, please let me know: we've got one "somewhere".)
