How do I duplicate a line or selection within Visual Studio Code?

Using Microsoft's Visual Studio Code, how do I duplicate a line of code and then move it up and down? (Similar to Sublime's cmd+shift+d behaviour)

It's a feature that I use constantly, and am struggling using Visual Studio Code without it.

The commands your are looking for are editor.action.copyLinesDownAction and editor.action.copyLinesUpAction.

You can see the associated keybindings by picking: File > Preferences > Keyboard Shortcuts

Windows:

Shift+Alt+Down and Shift+Alt+Up

Mac:

Shift+Option+Down and Shift+OptionUp

Linux:

Ctrl+Shift+Alt+Down and Ctrl+Shift+Alt+Up

(Might need to use numpad Down and Up for Linux)

Furthermore, commands editor.action.moveLinesUpAction and editor.action.moveLinesDownAction are the ones to move lines and they are bound to Alt+Down and Alt+Up on Windows and Mac and Ctrl+Down and Ctrl+Up on Linux.

You can find keyboard shortcuts from

> File > Preferences > Keyboard Shortcuts

Default Keyboard Shortcuts are,

Copy Lines Down Action : shift+alt+down

Copy Lines Up Action : shift+alt+up

Move Lines Up Action : alt+up

Move Lines Down Action : alt+down

Or you can override the keyboard shortcuts from > File > Preferences > Keyboard Shortcuts

And editing the keybindings.json

Example:

[    {        "key": "ctrl+d",        "command": "editor.action.copyLinesDownAction",        "when": "editorTextFocus"    },    {        "key": "ctrl+shift+up",        "command": "editor.action.moveLinesUpAction",        "when": "editorTextFocus"    },    {        "key": "ctrl+shift+down",        "command": "editor.action.moveLinesDownAction",        "when": "editorTextFocus"    }]

It miss an answer to this question, "How to duplicate selection of code" Similar to Sublime's cmd/ctrl+shift+d or Jetbrains' cmd/ctrl+d behaviour.

Install plugin Duplicate selection or line from VS Code Marketplace

This extension provides bindings for ctrl+d (Windows/Linux) and cmd+d (MacOS). To customize keyboard shortcuts Preferences -> Keyboard Shortcuts:

{
  "mac": "cmd+d",
  "key": "ctrl+d",
  "command": "geeebe.duplicateText",
  "when": "editorTextFocus"
}

Note : The shortcut does also the duplicate line so if you install it, remove your previous ctrl+d shortcut on copyLinesDownAction (if you did it before) otherwise duplicate selection can bug.

In VScode, they call this Copy Line Up and Copy Line Down

From the menu, go to: > File > Preferences > Keyboard Shortcuts

Check already assigned keyboard shortcut for this, or adjust yours.

Sometimes the default assigned shortcut may not work, mostly because of OS.

In my Ubuntu, I adjusted this to: Ctrl+Shift+D

In VSCode Ctrl+CCtrl+V duplicates the whole line below.

I prefer this to the accepted answer, because it only requires one hand to do this and feels way more natural.

The accepted answer will probably do it for most people, however Down sits the other side of the keyboard. So you have two options, use both hands on (Left Hand:L Shift+L Alt+ Right Hand:Up/Down), or with a single hand use the right R Shift+R Alt+Up/Down. The second option feels weird in my opinion. I'd rather use the option where my hand naturally sits on the keyboard, and if its one hand, even better.

Try ALT+SHIFT+UP/DOWN

It worked for me!

• For Jetbrains IDE Users who migrated to VSCode.

• Install(Anyone):

1. JetBrains IDE Keymap: Extension
2. vscode-intellij-idea-keybindings Extension (Preferred)

• Use this Intellij Darcula Theme: Extension

• The keymap has covered most of keyboard shortcuts of VS Code, and makes VS Code more 'JetBrains IDE like'.

• Above extensions imports keybindings from JetBrains to VS Code. After installing the extension and restarting VS Code you can use VS Code just like IntelliJ IDEA, Webstorm, PyCharm, etc.

For Windows :

To Copy Up - shift+alt+up

To Copy Down - shift+alt+down

For mac :

To Copy Up - shift+option+up

To Copy Down - shift+option+down

For linux :

To Copy Up - ctrl+shift+alt+8

To Copy Down - ctrl+shift+alt+2

Note : You may change your keyboard shortcuts keybinding for visual studio code by pressing ctrl+shift+p, then type open keyboard shortcut in the pallet and then hit enter so new file will be opened (Key board shortcut file) you can see all the shortcuts over their and can change keybindings by clicking twice over the respective keybinding and then by entering your own keybinding, finally hit enter.

Hope this will help somebody!

Note that for Ubuntu users (<= 17.4), Unity uses CTRL + ALT + SHIFT + Arrow Key for moving programs across virtual workspaces, which conflicts with the VS Code shortcuts. You'll need to rebind editor.action.copyLinesDownAction and editor.action.copyLinesUpAction to avoid the conflict (or change your workspace keybindings).

For Ubuntu 17.10+ that uses GNOME, it seems that GNOME does not use this keybinding in the same way according to its documentation, though if someone using vanilla workspaces on 17.10 can confirm this, it might be helpful for future answer seekers.

Simply go to the file -> preferences -> keyboard shortcuts There you can change any shortcut you like. search for duplicate and change it to whatever you always use in other editors. I changed to Ctrl+D

Duplicate line: alt + shift + △/▽

Move line up/down: alt + △/▽

If you coming from Sublime Text and do not want to relearn new key binding, you can use this extension for Visual Code Studio.

> Sublime Text Keymap for VS Code > >This extension ports the most popular Sublime Text keyboard shortcuts to Visual Studio Code. After installing the extension and restarting VS Code your favorite keyboard shortcuts from Sublime Text are now available.

This keymap will duplicate the current line if nothing is selected or duplicate the selected words.

1. Access:

   File/Preferences/Keyboard shortcuts

2. In the right top corner, click on Open Keyboard Shortcuts (JSON).

3. Insert this keymap:

    {
      "key": "shift+alt+d",
      "command": "editor.action.duplicateSelection"
    }
   

4. Use alt+arrows up/down to move the line (Default behaviour of VS Code).

Direct line duplication (without the clipboard step) is proposed by the Contextual Duplicate extension.

It is mapped on ctrl+K D

Problem

There seems to be a problem with the original "duplicate line down" shortcut on Ubuntu, mostly due to a conflict with an already existing workspace related shortcut on the operating system.

Workaround

However, an easy workaround is to simply CTRL+C (copies the entire line) and CTRL+V (pastes the copied line on to a new one)... Effectively, giving you the same end result.

Ctrl + c + v press these keys together not separate for windows

For those migrating from WebStorm/PhpStorm,

You could install IntelliJ IDEA Keybindings to keep using almost all the keyboard shortcuts as you did in Webstorm/Phpstorm.

So,

• Duplicate lines => CTRL + D
• Move a line/selection of code Up/Down => Ctrl + Shift + UP/DOWN

---

Also, here is a list of recommended VS Code extensions that will make your transition from WebStorm/Phpstorm much easier.

For Fedora 29 workstation (Gnome 3.30.2) and Ubuntu users.

Unbind unnecessary left/right workspace keyboard combinations, list them by terminal

$ gsettings list-recursively | grep -E "org.gnome.desktop.wm.keybindings move-to-workspace-|org.gnome.desktop.wm.keybindings switch-to-workspace-"

Unbind them

$ gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-left "[]"
$ gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-right "[]"
$ gsettings set org.gnome.desktop.wm.keybindings move-to-workspace-left "[]"
$ gsettings set org.gnome.desktop.wm.keybindings move-to-workspace-right "[]"

Reset duplicate shortcuts

• Super+Pgdown/PgUp , Ctrl+Alt+DownArrow/UpArrow
• Super+Shift+PgDown/PgUp , Ctrl+Alt+Shift+DownArrow/UpArrow

They can be easily reset to work with only one shortcut in Settings>Devices>Keyboard
Only type again Super+PgUp for "Move to workspace above" as an example.

Now with less duplicate shortcuts in fedora29 all vscode shortcuts for linux must work fine

For Linux users: I noticed what on Linux you quite an often need to use win key. For Windows combo is:
ctrl + shift + alt + up

then for Linux is same just add win key:
ctrl + shift + win + alt + up

I noticed that in a few combos now. Say ctrl + alt + L locks Linux, but ctrl + win + alt + L for Intellij formats code. Under Windows is just ctrl + alt + L to format the code.

in my last version Visual Studio Code 1.30.2 it wil be change automatically into

ctrl + D
