How do I duplicate a line or selection within Visu

问题:

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.

回答1:

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.

回答2:

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"
    }
]

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

回答4:

Try ALT+SHIFT+UP/DOWN

It worked for me!

回答5:

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.

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.

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.

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.

回答9:

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

It is mapped on ctrl+K D

回答10:

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

ctrl + D
