Gnome icons: Which icon would be used for "highlight"?

[Dotan Cohen]

Currently, the terrific Zim-wiki application uses the Underline Icon
for the Highlight feature:

Which Gnome icon would Gnome users recommend to use for Highlight
instead of the obviously-incorrect Underline Icon? Thanks for your
ideas!
