Duplicate line in Visual Studio Code

Question

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.

Answer 1

Click File > Preferences > Keyboard Shortcuts:

Search for copyLinesDownAction or copyLinesUpAction in your keyboard shortcuts

Usually it is SHIFT+ALT + ↓

Update for Ubuntu:

It seems that Ubuntu is hiding that shortcut from being seen by VSCode (i.e. it uses it probably by its own). There is an issue about that on GitHub.

In order to work in Ubuntu you will have to define your own shortcut, e.g. to copy the line using ctrl+shift+alt+j and CTRL +SHIFT + ALT + k you could use a keybindings.json like this:

[
    { "key": "ctrl+shift+alt+j", "command": "editor.action.copyLinesDownAction",
                                    "when": "editorTextFocus && !editorReadonly" },
    { "key": "ctrl+shift+alt+k", "command": "editor.action.copyLinesUpAction",
                                    "when": "editorTextFocus && !editorReadonly" }
]

Answer 2

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

Answer 3

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
