word 宏代码修改 关于”查找与替换“

hiqt

代码A
sub A()
Selection.Find.ClearFormatting
    Selection.Find.Replacement.ClearFormatting
    With Selection.Find
        .Text = "K?“
        .Replacement.Text = "K"
        .Forward = True
        .Wrap = wdFindContinue
        .Format = False
        .MatchCase = False
        .MatchWholeWord = False
        .MatchByte = True
        .MatchWildcards = False
        .MatchSoundsLike = False
        .MatchAllWordForms = False
    End With
    Selection.Find.Execute Replace:=wdReplaceAll

End Sub
代码B
sub B()
If Selection.Start <> Selection.End Then ActiveDocument.Range(Selection.Start, Selection.End).Find.Execute findtext:="K", replacewith:="W", Replace:=wdReplaceAll
End Sub


想把B的代码加入到A中，实现指定区域替换（变量替换），如何修改。
