I don't think you can change the "within" option. But you can change the other
settings, but not permanently.
Saved from a previous post:
Excel tries to help by remembering the last settings you used--except for the
first search in that session.
You can use that to your advantage.
You could make a dummy workbook and put it in your xlStart folder. Have a
macro in that workbook that does a find (and sets all the stuff the way you
like). Then closes and gets out of the way.
Option Explicit
Sub auto_open()
'change the settings the way you like
Worksheets(1).Cells.Find What:="", After:=ActiveCell, _
LookIn:=xlValues, _
LookAt:=xlPart, SearchOrder:=xlByColumns, _
SearchDirection:=xlNext, MatchCase:=False
ThisWorkbook.Close savechanges:=False
End Sub
The workbook opens, does a find (to fix your settings) and then closes to get
out of the way.
If you're new to macros, you may want to read David McRitchie's intro at:

But if you do an Edit|Find and change anything, then those changed settings will
be remembered.
