[visual-studio-code] Duplicate line in Visual Studio Code

I am trying to find the shortcut for duplicating a line in Visual Studio Code (I am using 1.3.1) I tried the obvious CTRL + D but that doesn't seem to work.

This question is related to visual-studio-code

The answer is


VC Code Version: 1.22.2 Go to: Code -> Preferences -> Keyboard Shortcuts (cmd + K; cms + S); Change (edit): "Add Selection To Next Find Match": "cmd + what you want" // for me this is "cmd + D" and I pur cmd + F; Go to "Copy Line Down": "cmd + D" //edit this and set cmd + D for example And for me that's all - I use mac;


Update that may help Ubuntu users if they still want to use the ? and ? instead of another set of keys.

I just installed a fresh version of VSCode on Ubuntu 18.04 LTS and I had duplicate commands for Add Cursor Above and Add Cursor Below

Original Keybindings

I just removed the bindings that used Ctrl and added my own with the following

Copy Line Up

Ctrl + Shift + ?

Copy Line Down

Ctrl + Shift + ?

New Keybindings


The duplicate can be achieved by CTRL+C and CTRL+V with cursor in the line without nothing selected.


Ubuntu :

  • Duplicate Line Up : Ctrl + Alt + Shift + 8
  • Duplicate Line Down : Ctrl + Alt + Shift + 2

Mac:

Duplicate Line Down :shift + option + ?

Duplicate Line Up:shift + option + ?


Windows:

Duplicate Line Down : Ctrl + Shift + D


Another 2 very usefull shortcuts are to move lines selected up and down, like sublime text does...

{
  "key" : "ctrl+shift+down", "command" : "editor.action.moveLinesDownAction",
  "when" : "editorTextFocus && !editorReadonly"
},

and

{
  "key" : "ctrl+shift+up", "command" : "editor.action.moveLinesUpAction",
  "when" : "editorTextFocus && !editorReadonly"
}

Use the following: Shift + Alt+(? or ?)


It's possible to create keybindings that are only active when Vim for VSCode is on and in a certain mode (i.e., "Normal", "Insert", or "Visual").

To do so, use Ctrl + Shift + P to open up VSCode's Command Palette, then search for "Preferences: Open Keyboard Shortcuts (JSON)"--selecting this option will open up keybindings.json. Here, custom bindings can be added.

For example, here are the classic VSCode commands to move/duplicate lines tweaked for ease of use in Vim..

    [
      {
        "key": "alt+j",
        "command": "editor.action.moveLinesDownAction",
        "when": "editorTextFocus && vim.active && vim.mode == 'Normal'"
      },
      {
        "key": "alt+shift+j",
        "command": "editor.action.copyLinesDownAction",
        "when": "editorTextFocus && vim.active && vim.mode == 'Normal'"
      },
      {
        "key": "alt+k",
        "command": "editor.action.moveLinesUpAction",
        "when": "editorTextFocus && vim.active && vim.mode == 'Normal'"
      },
      {
        "key": "alt+shift+k",
        "command": "editor.action.copyLinesUpAction",
        "when": "editorTextFocus && vim.active && vim.mode == 'Normal'"
      },
    ]

Now we can use these Vim-friendly commands in VSCode!

  • Alt + J to move a line down
  • Alt + K to move a line up
  • Shift + Alt + J to duplicate a line down
  • Shift + Alt + K to duplicate a line up

You can use the following depending on your OS:

Windows:

Shift+ Alt + ? or Shift+ Alt + ?

Mac:

Shift + Option + ? or Shift +Option + ?

Linux:

Ctrl+Shift+Alt+? or Ctrl+Shift+Alt+?

Note: For some linux distros use Numpad arrows


Search for copyLinesDownAction or copyLinesUpAction in your keyboard shortcuts

Usually, it is SHIFT+ALT+?


There is a new command in v1.40: editor.action.duplicateSelection unbound to any keybinding.

Duplicate selection

We have added a new action named Duplicate Selection. When executed, the current selection will be duplicated and the result will be selected. When there is no selection, the current line will be duplicated, all without writing to the system clipboard.
