I don't think you could change the default, but you could add the paste
special|Values button to your favorite toolbar.
You can get to via Tools|customize|Commands Tab|Edit category
Drag the "Paste Values" icon to your favorite toolbar (or create new customized
toolbar).
Other people have created macros that they assign to shortcut keys (and load
with their personal.xl* file so it's always available).
Something like:
Option Explicit
Sub MyPasteSpecialValues()
If Application.CutCopyMode = False Then
Beep
Else
ActiveCell.PasteSpecial Paste:=xlPasteValues
End If
End Sub
The assign it a nice shortcut key (Ctrl-Shift-V??).
Tools|Macro|Macros
Select the macro
Click Options
type in your shortcut key (case is important)
Ok out of that dialog
Cancel out of this one.
