No but you can create a macro to do this. First, paste this code into the
VBA editor (Alt+F11):
Sub ChangeReferenceStyle()
With Application
If (.ReferenceStyle = xlA1) Then
.ReferenceStyle = xlR1C1
End
Else:
.ReferenceStyle = xlA1
End If
End With
End Sub
Then, Tools->Macro->"Macros..." Select the macro, hit "Options" and enter
the shortcut key you would like to toggle this.
