is it poss. to freeze a scrolling window

[AC]

one field contains lengthy text and is formatted to scroll. a second field is a repeating field that contains keywords that I input based on information from the first field and is the related field for a portal from another database. is there a formatting step that would allow me to freeze the first field as I edit the second field so that the first field does not return to the beginning of the text? If not, are there suggestions for other ways to solve this ... I am considering creating a new window containing only the second field, but don't know if that's the best solution. Thanks.
