Visual Studio : short cut Key : Duplicate Line

 

Is there a shortcut for Duplicate Line command in Visual Studio 2008?

Some similar examples:

  • in Notepad++ , I can duplicate the current line with: Ctrl+D
  • in EditPlus : Ctrl+J
  • in NetBeans : Ctrl+Shift+↓/↑
  • in Eclipse , Ctrl+Alt+↓/↑
  • in Vi/Vim , yyp
  • etc.

    • Built in method using clipboard

    As @cand mentioned, you can just do Ctrl + C ; Ctrl + V.

    Ctrl + C will copy the line if nothing is selected.

    Macro solution

    If you'd like to implement a more complete solution, perhaps to create a simpler keyboard shortcut or you don't want to effect the clipboard, see this guide:

    Duplicate line command for Visual Studio

    Visual Basic: 

    Imports System
Imports EnvDTE
Imports EnvDTE80
Imports System.Diagnostics

Public Module DuplicateLastLineModule
Sub DuplicateLine()
Dim line As String
DTE.ActiveDocument.Selection.StartOfLine(0)
DTE.ActiveDocument.Selection.EndOfLine(True)
line = DTE.ActiveDocument.Selection.Text
DTE.ActiveDocument.Selection.EndOfLine()
DTE.ActiveDocument.Selection.NewLine()
DTE.ActiveDocument.Selection.StartOfLine(0)
DTE.ActiveDocument.Selection.Text = line
End Sub
End Module

    To create the macro, just go to the macro explorer ("Tools->Macros->Macro Explorer" or Alt+F8) and copy paste the code in a new module. Now just assing a keyboard shortcut to it:

  • go to Tools->Options...
  • under Environment, click Keyboard
  • in the "Show Commands Containing" textbox, enter "duplicate" (this according to the name you gave the module.)
  • you should now see the macro in the list below
  • choose "Text Editor" from the "Use new shortcut in" list
  • set focus in the "Press shortcut keys" textbox and hit the combination on the keyboard you whish to use for it (Ctrl+Shift+D in my case)
  • hit the "Assign" button
  • you should now see the shortcut in the "Shortcuts for selected command" textbox
  • hit the OK button

    • And that's it. Enjoy!

    There's a free extension you can download here that lets you duplicate lines without replacing the clipboard contents.

    By default its bound to Alt + D, but you can change it to anything you want by going to Tools->Options->Environment->Keyboard. Type "Duplicate" in the search box and look for "Edit.DuplicateSelection" and edit the shortcut to whatever you want. I prefer Ctrl + D to be consistent with other editors.

    It's simple Ctrl + C ; Ctrl + V , check this link. As long as you don't select any text, this will duplicate the line the cursor is over when you press Ctrl+C.
