Dear Bob,
You can tag the appropriate line and configure the tag to highlight
the text. Here's a small example:

>>> from Tkinter import *
>>> import Pmw
>>> r=Tk()
>>> t=Pmw.ScrolledText(r)
>>> t.pack()
>>> t.insert(END,"one\ntwo\nthree\nfour\nfive\nsix\nseven\n")
>>> t.component("text").tag_add("standout","2.0","2.end")
>>> t.component("text").tag_configure("standout",background="yellow")

Regards,
Matt
