Visual Studio : short cut Key : Duplicate Line

Question

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.

Just for info, one of the many benefits offered by ReSharper is the ability to do this. — AakashM, Feb 17 '10 at 08:08
https://visualstudiogallery.msdn.microsoft.com/830a6482-3b8f-41a8-97b5-b9c581e5ad8b Download this and alt + D will duplicate your selection or if nothing is highlighted it will duplicate the entire line. Unfortunately visual basic macros don't seem to work in 2013, only js macros. — ss7, May 17 '15 at 05:29
OMG, what is the problem to assign combination a person like for duplicating line??? I used to Eclipse. And Ctrl + D is for removing line. Why it's so complicated in VS??? — Andrii Muzychuk, Aug 02 '15 at 12:46
@mghhgm below is the answer you're looking for.(shift+alt+down or shift+alt+up) — Victor Barrantes, Dec 01 '16 at 05:55
The vim example is not duplicating, it's ctrl+c;ctrl+v. "Yank" cuts, and p pastes. It's not quite the same as the other examples. — ANeves, May 04 '17 at 17:56
This has now become a default command in Visual Studio 2017, bound to Ctrl-E, V, but you can bind it to anything. Can duplicate line (if nothing selected) or duplicate selection, see: https://dailydotnettips.com/did-you-know-now-you-can-duplicate-line-of-code-without-loosing-your-clipboard-content-within-visual-studio/ — Abel, May 27 '18 at 00:09

In Visual Studio 2022

Ctrl + E, V

In Visual Studio 2019

Ctrl + D

In Visual Studio 2017 (v15.6 and after)

Ctrl + D

In Visual Studio 2017 (pre v15.6)

(edit) This feature is now built-in in VS2017: Ctrl + E, V duplicates a line if nothing is selected, or duplicates selection. You can assign it to a different key combination, or find it in the menu:

See this reference for more information.

Pre VS2017, 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 (pre VS2017)

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:

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 assign 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 wish 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!

I just tried it, and it's interesting that it repeats some extra characters when there is a "server-side code block" with short tags, like this: `
Profile.UserName: <%=Profile.UserName %>
` - after duplicating this line using this macro, it becomes the following: `
Profile.UserName: <%=Profile.UserName %>
%>`. As you can see, the last part is "repeated". When there are no server side code blocks in it, it works OK. Do you know a workaround for that? By the way, another interesting thing I experienced is that this macro is relatively "slow", which I didn't expect... :) – Sk8erPeter May 07 '12 at 13:49

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.

Matthew, you have to click the HERE link and install the extension. THEN you have to close visual studio and reopen it. THEN you have to go to Tools ==> Options ==> Environment ==> Keyboard and THEN you have to type Duplicate and you will see it. Then you can press F4 so it acts like QEDIT or whatever you want and life will be good. – ggb667 Nov 11 '14 at 21:20

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.

I've only found this one. However it's not that bad - of course easier would be to use ctrl+D, but if You want to duplicate 1 line in 100 copies You can do it using ctrl+c (without need to select anything, just put command prompt over wanted line) + 100 times ctrl+v. It's only one set of keystrokes more than ctrl+d solution. It can be more problematic if You want to do more complex duplication. – cand Jun 21 '10 at 15:27
@Mason240 That was my initial reaction as well to the quoted part in the accepted answer however the additional information 'As long as you don't select any text, this will duplicate the line the cursor is over...' makes this an ideal solution in my case. – RyanfaeScotland Aug 19 '14 at 09:57
I think this DOES do what he wants but it screws up the clipboard. A better solution is the one Ben proposed. – ggb667 Nov 11 '14 at 21:22
One addendum to this is that you can use the visual studio clipboard ring afterwards to get to a previously copied item. Ctrl+Shift+V. – Error 454 Dec 10 '14 at 20:46
This just plain does not work "as long as no text is selected". Nope, it just copies nothing thus never changing whats in the clipboard and then pasting in whatever was there. Stupid this has 76 upvotes. – user9993 Apr 07 '17 at 13:00
That's answering how to use the clipboard, not how to duplicate a line. What if you want to duplicate a line without replacing clipboard content? – Antony Booth Nov 16 '17 at 16:23
_If you don't want to override current content of the clipboard and still need to copy/paste_: just select the text, press control and drag and drop the text where you need it to be copied. – chviLadislav Jun 26 '19 at 07:53

This is the default shortcut if you are using Resharper's "Resharper 2.x or IntelliJ IDEA" keyboard scheme. Resharper has you select the keyboard mapping during the install. "Visual Studio" keyboard scheme is one of the choices. If you pick "Visual Studio" keyboard scheme, then Ctrl+D will be mapped to something else. – GeoMac Apr 28 '17 at 12:44
That's an answer to a ReSharper question. – Antony Booth Nov 16 '17 at 16:22
Note that this also works when multiple lines are selected, i.e. you can duplicate a whole bunch of code, not just one line. Downside of course being that resharper isn't free (but it seems the .Net world is used to that more than the Java world I come from). – Amos M. Carpenter Jan 19 '18 at 05:31

While I realize this is not a keyboard shortcut, I figured I would add this, as it does not require the usage of the clipboard and might help some people.

Highlight the row you want to duplicate. Press control, mouse click the highlighted text, and drag to where you want to go to. It will duplicate the highlighted text.

I've been using the macro that Wael posted: Duplicate line command for Visual Studio, but it stopped working a week ago, I assumed because of a Windows update. And I was correct, as of February 2014, Macros have been disabled in VS2010 (and 2008 apparently).

To fix this you'll either have to uninstall the security updates, or add one line of code into the config files as shown here.

On a 64-bit Windows machine default paths to these files are:

C:\Program Files (x86)\Common Files\Microsoft Shared\VSA\9.0\VsaEnv\vsaenv10.exe.config

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe.config

...
<configuration>
    <runtime>
        <AllowDComReflection enabled="true"/>
        ...

You MUST run your text editor with admin rights or it won't work! Hopefully this helps anyone else who suddenly has their macro functionality pulled out from underneath them.

Edit menu keyboard shortcuts with: ctrl+k and ctrl+s

Edit "Copy Line Down" (Shift + Alt + DownArrow) to your your own shortcut.

You can find it, with the command ID: editor.action.copyLinesDownAction

For me, It's ctrl+d

Just put your mouse on the line to copy and do CTRL+C ,afterwards CTRL+V on the same line. Works like magic :-)

Ctrl + D is a new shortcut introduced in VS 2017 v15.6 that seems to do the exact thing that Ctrl + E, V

Ctrl + D will duplicate the line the cursor is in and insert it right below the line in focus. If you’d like to duplicate a specific set of code, simply select the portion of code you want to duplicate before invoking the duplicate code command.

It won't affect your clipboard

I use application link:AutoHotkey with below code saved in CommentDuplikateSaveClipboard.ahk file. You can edit/remove shortcuts it is easy.
I have link to this file "Shortcut to CommentDuplikateSaveClipboard.ahk" in Autostart in windows.
This script protect your clipboard.
If you are more curious you would add shortcuts to thisable/enable script.
I sometimes use very impressive Multi Clipboard script to easy handle with many clips saved on disk and use with CTRL+C,X,V to copy,paste,cut,next,previous,delete this,delete all.

;CommentDuplikateSaveClipboard.ahk

!c:: ; Alt+C === Duplicate Line
^d:: ; Ctrl+D
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{HOME}{SHIFTUP}{CTRLDOWN}c{CTRLUP}{END}{ENTER}{CTRLDOWN}v{CTRLUP}{HOME}
Clipboard := ClipSaved
ClipSaved =
return

!x:: ; Alt+X === Comment Duplicate Line
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{HOME}{SHIFTUP}{CTRLDOWN}c{CTRLUP}{LEFT}//{END}{ENTER}{CTRLDOWN}v{CTRLUP}{HOME}
Clipboard := ClipSaved
ClipSaved =
return

!z:: ; Alt+Z === Del uncomment  Line
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{UP}{END}{SHIFTUP}{DEL}{HOME}{DEL}{DEL}
Clipboard := ClipSaved
ClipSaved =
return

!d:: ; Alt+D === Delete line
Send, {END}{SHIFTDOWN}{UP}{END}{SHIFTUP}{DEL}
return

!s:: ; Alt+S === Swap lines
ClipSaved := ClipboardAll
Send, {END}{SHIFTDOWN}{UP}{END}{SHIFTUP}{CTRLDOWN}x{CTRLUP}{UP}{END}{CTRLDOWN}v{CTRLUP}{HOME}
Clipboard := ClipSaved
ClipSaved =
return

!a:: ; Alt+A === Comment this line, uncomment above
Send, {END}{HOME}//{UP}{HOME}{DEL}{DEL}
return

In Visual Studio 2010 you copy the entire line the cursor is on with CTRL + INSERT then you can use Ctrl + V or SHIFT + INSERT to paste it.

The command you want is Edit.Duplicate. It is mapped to CtrlE, CtrlV. This will not overwrite your clipboard.

Not an answer, just a useful addition: As a freebie, I just invented (well... ehm... adjusted the code posted by Lolo) a RemoveLineOrBlock macro. Enjoy!

Imports System
Imports EnvDTE
Imports EnvDTE80
Imports EnvDTE90
Imports EnvDTE90a
Imports EnvDTE100
Imports System.Diagnostics

Public Module RemoveLineOrBlock

    Sub RemoveLineOrBlock()
        Dim selection As TextSelection = DTE.ActiveDocument.Selection
        Dim lineNumber As Integer
        Dim line As String

        If selection.IsEmpty Then
            selection.StartOfLine(0)
            selection.EndOfLine(True)
        Else
            Dim top As Integer = selection.TopLine
            Dim bottom As Integer = selection.BottomLine

            selection.MoveToDisplayColumn(top, 0)
            selection.StartOfLine(0)

            selection.MoveToDisplayColumn(bottom, 0, True)
            selection.EndOfLine(True)
        End If

        selection.LineDown(True)
        selection.StartOfLine(vsStartOfLineOptions.vsStartOfLineOptionsFirstColumn,True)

        selection.Delete()

        selection.MoveToDisplayColumn(selection.BottomLine, 0)
        selection.StartOfLine(vsStartOfLineOptions.vsStartOfLineOptionsFirstText)

    End Sub

End Module

in VS2019 and also in VS2017 you can select Tools->Options->Keyboard and you can choose in the scheme drop-down Resharper (Visual Studio) option, and you will get a mapping like if you were using Resharper, in this case Ctrl + D will do the trick for duplicating the line. Anyways, based on the documentation this should be out of the gate in Visual Studio 2017 Version 15.8 or greater

On Linux Mint, you can do;

**Ctrl + Alt + Shift + 2** => *Duplicate up*

**Ctrl + Alt + Shift + 8** => *Duplicate down*

For visual studio 2010, try using these commands for quick line duplication (uses clipboard):

Click on the line you want to copy. Ctrl + C will copy that line.
Then press Ctrl + Shift + Enter to insert a blank below insertion point

(Alternatively use Ctrl + Enter to insert a blank line above the insertion point.)
Then simply use Ctrl + V to paste the line.
