对于Visual Studio Code 2019:

使用ctrl+k和ctrl+s编辑菜单键盘快捷键

编辑“向下复制一行”(Shift + Alt + DownArrow)到你自己的快捷方式。

您可以通过命令ID: editor.action.copyLinesDownAction找到它

对我来说，ctrl+d

在visual studio代码(WebMatrix)中:

向下复制行:Shift + Alt +向下

复制线:Shift + Alt +向上

删除行:Ctrl + Shift + k

Ctrl + C + V适用于我在VS2012没有扩展。

Visual Studio Code: 2020年5月(版本1.46) Shift +向上/向下箭头:复制代码行

在Linux Mint上，你可以这样做; Ctrl + Alt + Shift + 2 =>复制 Ctrl + Alt + Shift + 8 =>复制下来

如果你喜欢使用CTRL+ALT+UP或CTRL+UP+DOWN复制eclipse样式的行(或块)，下面我发布了用于此目的的宏:

        line = selection.Text

        selection.MoveToDisplayColumn(selection.BottomLine, 0)
        selection.Insert(vbNewLine & line)
        selection.MoveToDisplayColumn(lineNumber, 0)
    End Sub
End Module
