Hide/Unhide an indirectly referenced column

I want to automatically hide/unide columns in a worksheet based on the contents of a cell. The cell contains the name of the column that should be hidden. Using the following VBA code, I can get the unhide/hide to work fine, but not sure on how to reference the contents of the cell instead of hardcoding the column to hide/unhide.

The column that I want to hide is defined in cell B12. The contents of cell B12 is currently something like "F" to indicate column F.

Can someone help?

Option Explicit
 
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Set Target = Range("B13")
    Select Case Target.Value
    Case "Visable"
        Worksheets("VQ").Columns("F:F").EntireColumn.Hidden = False
    Case "Hidden"
        Worksheets("VQ").Columns("F:F").EntireColumn.Hidden = True
    Case Else
        Exit Sub
    End Select

End Sub
