Reformat all instances of a particular phrase

Problem

Suppose you're doing a class lesson in PowerPoint and want to highlight all instances of a particular phrase by making it bold or changing its color, etc.
It's possible to do the job manually, but it could be very tedious. Nearly, but not quite, as tedious as reading my prose.

Using a simple macro, though, you can have the job done in seconds:

Solution

Sub FormatThePhrase()

Dim oSl As Slide
Dim oSh As Shape
Dim lStartPos As Long
Dim sSearchPhrase As String

' EDIT THIS TO REFLECT THE PHRASE YOU'RE LOOKING FOR
sSearchPhrase = "my phrase"

For Each oSl In ActivePresentation.Slides
    For Each oSh In oSl.Shapes
        If oSh.HasTextFrame Then
            If oSh.TextFrame.HasText Then
                lStartPos = InStr(UCase(oSh.TextFrame.TextRange.Text), UCase(sSearchPhrase))
                If lStartPos > 0 Then
                    ' one example of how you can change the text formatting
                    ' do whatever else is needed here:
                    oSh.TextFrame.TextRange.Characters(lStartPos, Len(sSearchPhrase)).Font.Bold = True
                End If
            End If
        End If
    Next
Next

End Sub
