Hi Naomi
I _suspect_ that you're talking about shading of the fields. If that's the case, then you can create a user form with three option buttons and an OK button. The routine for the OK button _could_ look like the following
Private Sub cmdOk_Click(
Dim iFieldShading As Intege
Select Case Tru
Case Me.optAlway
iFieldShading = wdFieldShadingAlway
Case Me.optNeve
iFieldShading = wdFieldShadingNeve
Case Me.optWhenSelecte
iFieldShading = wdFieldShadingWhenSelecte
End Selec
ActiveWindow.View.FieldShading = iFieldShadin
Me.Hid
Unload M
End Su
If you really do mean "highlighting", then you can run a replace routine, as describe at the Word MVP site
"Using a macro to replace text where ever it appears in a document including Headers, Footers, Textboxes, etc." at

HTH,
