在WORD中用VBA实现光标移动与内容选择

在WORD中如何用VBA宏语言选定一行、一段，删除一行、一段，移动光标至行首、行尾、段首、段尾等。

请看以下内容。Sub MoveToCurrentLineStart()
    '移动光标至当前行首
    Selection.HomeKey unit:=wdLine
End SubSub MoveToCurrentLineEnd()
    '移动光标至当前行尾
    Selection.EndKey unit:=wdLine
End SubSub SelectToCurrentLineStart()
    '选择从光标至当前行首的内容
    Selection.HomeKey unit:=wdLine, Extend:=wdExtend
End SubSub SelectToCurrentLineEnd()
    '选择从光标至当前行尾的内容
    Selection.EndKey unit:=wdLine, Extend:=wdExtend
End SubSub SelectCurrentLine()
    '选择当前行
    Selection.HomeKey unit:=wdLine
    Selection.EndKey unit:=wdLine, Extend:=wdExtend
End SubSub MoveToDocStart()
    '移动光标至文档开始
    Selection.HomeKey unit:=wdStory
End SubSub MoveToDocEnd()
    '移动光标至文档结尾
    Selection.EndKey unit:=wdStory
End SubSub SelectToDocStart()
    '选择从光标至文档开始的内容
    Selection.HomeKey unit:=wdStory, Extend:=wdExtend
End SubSub SelectToDocEnd()
    '选择从光标至文档结尾的内容
    Selection.EndKey unit:=wdStory, Extend:=wdExtend
End SubSub SelectDocAll()
    '选择文档全部内容（从WholeStory可猜出Story应是当前文档的意思）
    Selection.WholeStory
End SubSub MoveToCurrentParagraphStart()
    '移动光标至当前段落的开始
    Selection.MoveUp unit:=wdParagraph
End SubSub MoveToCurrentParagraphEnd()
    '移动光标至当前段落的结尾
    Selection.MoveDown unit:=wdParagraph
End SubSub SelectToCurrentParagraphStart()
    '选择从光标至当前段落开始的内容
    Selection.MoveUp unit:=wdParagraph, Extend:=wdExtend
End SubSub SelectToCurrentParagraphEnd()
    '选择从光标至当前段落结尾的内容
    Selection.MoveDown unit:=wdParagraph, Extend:=wdExtend
End SubSub SelectCurrentParagraph()
    '选择光标所在段落的内容
    Selection.MoveUp unit:=wdParagraph
    Selection.MoveDown unit:=wdParagraph, Extend:=wdExtend
End SubSub DisplaySelectionStartAndEnd()
    '显示选择区的开始与结束的位置，注意：文档第1个字符的位置是0
    MsgBox ("第" & Selection.Start & "个字符至第" & Selection.End & "个字符")
End SubSub DeleteCurrentLine()
    '删除当前行
    Selection.HomeKey unit:=wdLine
    Selection.EndKey unit:=wdLine, Extend:=wdExtend
    Selection.Delete
End SubSub DeleteCurrentParagraph()
    '删除当前段落
    Selection.MoveUp unit:=wdParagraph
    Selection.MoveDown unit:=wdParagraph, Extend:=wdExtend
    Selection.Delete
End Sub
