You are referring to navigation not cell wrap.
The option controlling the Enter key can be found at
Tools (menu), Options (menu), Edit (tab),
settings: [x] Move selection after Enter {Down|Up|Right|Left}
Though I don't really think you need to change it, you can use
the arrow key.
But an Event Macro sounds more useful for your purpose.
Worksheet Events and Workbook Events
Worksheet_SelectionChange (#ws_sc)
Worksheet_SelectionChange to prevent entry past a column
http://www.mvps.org/dmcritchie/excel/event.htm#ws_sc
Modified for your use: to not procede beyond column 8
and only be effect from rows 13 through 54
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.column < 8 then exit sub
IF Target.Row < 13 or Target.ZRow > 54 then exit sub
On error resume next 'MUST reenable events...
Application.EnableEvents = False
ActiveCell.Offset(1, 1 - Target.Column).Select
Application.EnableEvents = True
End Sub
Unlike regular macros which are installed in regular modules,
Worksheet Events are installed with the worksheet by right-clicking on
the sheettab, choose 'view code', and then paste in your macro.
BTW, Cell wrap is a format, cell, alignment option that
formats the cell to wrap text within a cell rather
than extending to display into the adjacent cells
unless they have a value, in which case the display
would be truncated.
