Microsoft Powerpoint has a surprisingly powerful equation editor, which also allows to use latex macros such as \alpha to get $\alpha$.

I’ve blogged about the equation editor before but one pet peeve of mine was that I like to have my math in a different color, but never found a way to do this automatically. I finally decided to invest the time and find out how to do it. After a mere several years of investigation, I am happy to report that it is in fact possible to do so using Visual Basic for Applications (VBA).

You can view the developer tab by following these instructions, and then click on “macros”, type a name such as All_eqs and click on “create” at which point you can add the following code:

Sub All_eqs()

Dim oSld As Slide
Dim oShp As Shape
Dim oShapes As Shapes

For Each oSld In ActivePresentation.Slides
Set oShapes = oSld.Shapes
For Each oShp In oShapes
If oShp.HasTextFrame Then
If oShp.TextFrame.HasText Then
With oShp.TextFrame.TextRange
For x = 1 To .Characters.Count
If .Characters(x).Font.Name = "Cambria Math" Then
.Characters(x).Font.Color.RGB = RGB(0, 112, 192)
End If
Next x
End With

End If
End If
Next oShp
Next oSld
End Sub
