在 Mr.Abao'S Blog 上看到的，VBA编程时要参考，特地转一下，另外由于嵌入到VBScript脚本中编程，对一些常量我给出了声明：

Const wdCharacter = 1
Const wdExtent = 1
Const wdExtend = 1
Const wdGoToBookmark = -1
Const wdLine = 5
Const wdCell = 12
Const wdTableFormatSimple2 = 2
Const wdAlignParagraphRight = 2
Const wdYellow = 7
Const wdToggle = 9999998
Const wdAlignParagraphCenter = 1
Const wdSentence = 3
Const wdParagraph = 4
Const wdStory = 6
Const wdMove = 0

下面我将 Mr.Abao'S Blog 的内容转帖（略作修改，主要是注释部分增加了VBScript的脚本写法）：在WORD中用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。

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