Matt,

Copy the code below, right-click the sheet tab, select "View Code" and paste the code into the
window that appears.

I've use the change event because you talk about typing in and not just selecting as cell

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Column < 1 Then Exit Sub
If Target.Cells.Count 1 Then Exit Sub
If Target.Value = "" Then Exit Sub
Application.EnableEvents = False
Target.Value = "Test - " & Target.Value & " - Test"
Application.EnableEvents = True
End Sub

Can I use selection_change to modify the current cell?

e.g I want to type 1234 into any cell in column A and have it change to "Test - 1234 - Test" upon
leaving the cell

TIA

Matt
