I have read around the subject and am familiar with the following,

Selection.Find.ClearFormatting
 With Selection.Find
    .Text = "xxx"
    .Replacement.Text = ""
    .Forward = True
    .Wrap = wdFindContinue
    .Format = False
    .MatchCase = False
    .MatchWholeWord = False
    .MatchWildcards = False
    .MatchSoundsLike = False
    .MatchAllWordForms = False
 End With
 Selection.Find.Execute
However, this is geared to text found in the document and not the textbox that is being inputted and the selection element means you have to specify each word to look for. How can it be adapted to search for highlighted words in a range, in the textbox?

EverythingI have found seems to be a variation on the above only.
