Sub MoveToCurrentLineStart()
‘移动光标至当前行首
Selection.HomeKey unit:=wdLine
End Sub
Sub MoveToCurrentLineEnd()
‘移动光标至当前行尾
Selection.EndKey unit:=wdLine
End Sub
Sub SelectToCurrentLineStart()
‘选择从光标至当前行首的内容
Selection.HomeKey unit:=wdLine, Extend:=wdExtend
End Sub
Sub SelectToCurrentLineEnd()
‘选择从光标至当前行尾的内容
Selection.EndKey unit:=wdLine, Extend:=wdExtend
End Sub
Sub SelectCurrentLine()
‘选择当前行
Selection.HomeKey unit:=wdLine
Selection.EndKey unit:=wdLine, Extend:=wdExtend
End Sub
Sub MoveToDocStart()
‘移动光标至文档开始
Selection.HomeKey unit:=wdStory
End Sub
Sub MoveToDocEnd()
‘移动光标至文档结尾
Selection.EndKey unit:=wdStory
End Sub
Sub SelectToDocStart()
‘选择从光标至文档开始的内容
Selection.HomeKey unit:=wdStory, Extend:=wdExtend
End Sub
Sub SelectToDocEnd()
‘选择从光标至文档结尾的内容
Selection.EndKey unit:=wdStory, Extend:=wdExtend
End Sub
Sub 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 Sub
Sub MoveToCurrentParagraphStart()
‘移动光标至当前段落的开始
Selection.MoveUp unit:=wdParagraph
End Sub
Sub MoveToCurrentParagraphEnd()
‘移动光标至当前段落的结尾
Selection.MoveDown unit:=wdParagraph
End Sub
Sub SelectToCurrentParagraphStart()
‘选择从光标至当前段落开始的内容
Selection.MoveUp unit:=wdParagraph, Extend:=wdExtend
End Sub
Sub SelectToCurrentParagraphEnd()
‘选择从光标至当前段落结尾的内容
Selection.MoveDown unit:=wdParagraph, Extend:=wdExtend
End Sub
Sub SelectCurrentParagraph()
‘选择光标所在段落的内容
Selection.MoveUp unit:=wdParagraph
Selection.MoveDown unit:=wdParagraph, Extend:=wdExtend
End Sub
Sub 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 Sub
Sub DeleteCurrentLine()
‘删除当前行
Selection.HomeKey unit:=wdLine
Selection.EndKey unit:=wdLine, Extend:=wdExtend
Selection.Delete
End Sub
Sub DeleteCurrentParagraph()
‘删除当前段落
Selection.MoveUp unit:=wdParagraph
Selection.MoveDown unit:=wdParagraph, Extend:=wdExtend
Selection.Delete
End Sub
