I cannot find a way to comment and uncomment multiple lines of code in Visual Studio Code.

Is it possible to comment and uncomment multiple lines in Visual Studio Code using some shortcut? If yes, how to do it?

Windows: Shift + Alt + A

Linux: Shift + Ctrl + A

macOS: Shift + Option + A

Here you can find all the keyboard shortcuts:

Windows Visual Studio Code shortcuts

Linux Visual Studio Code shortcuts

macOS Visual Studio Code Shortcuts

PS: I prefer Ctrl + Shift + / for toggling block comments because Ctrl + / is shortcut for toggling line comments, so it's naturally easier to remember. To do so, just click on the settings icon in the bottom left of the screen and click 'Keyboard Shortcuts' and find "toggle block...". Then click and enter your desired combination.

This is probably not the top voted answer because of how VS Code works for different languages. For python code, the "comment block" command Alt + Shift + A actually wraps the selected text in a multiline string, whereas Ctrl + / is the way to toggle any type of comment (including a "block" comment as asked here).
You can find the comment options in the Edit menu if you forget the keyboard shortcuts.
ctrl + shift + A worked for me for adding multi-line comment.
CTRL + / works great for any commenting with the Vim emulator extension.
NOTE for Mac users: in general, shortcuts that are Ctrl+Whatever on Windows are Command+Whatever on Mac; In particular this is Command+/ to toggle or Command+K,Command+C to add a layer of comments.

First, select the lines you want to comment/uncomment (Ctrl + L is convenient to select a few lines)

Then:

  • To toggle line comments, execute editor.action.commentLine (Ctrl + / on Windows)

    or

  • To add line comments, execute editor.action.addCommentLine (Ctrl + K, Ctrl + C)

    To remove line comments, execute editor.action.removeCommentLine (Ctrl + K, Ctrl + U)

    or

  • To toggle a block comment, execute editor.action.blockComment (Shift + Alt + A)

See the official documentation: Key Bindings for Visual Studio Code

Sadly, cmd+/ is not a valid shortcut for a German (Mac) keyboard. FWIW: I changed it to { "key": "cmd+shift+7", "command": "editor.action.commentLine", "when": "editorTextFocus" } to match Atom.
On mac, it's cmd+- (cmd and minus).
Weird, with me it's cmd+= (macos sierra and vscode 161)
I'm using it on js file. But it doesn't work for /* .. */ multiline comment. instead, it puts/removes '//' infront of all the lines selected
@Mario: I struggled for a long time, until I finally decides to move from my Swiss-German Layout to the US-Layout. The umlauts are the only Problem, but on Mac you get used to the "workaround" fast. The US Layout is the standard for (nearly) all programs, when it comes to shortcuts, so I would consider switching.

How to comment out multiline / single line in Visual Studio Code:

macOS:

Shift + Option + A:

/* multiline
   comment */

CMD + /:

// Single line comment

Windows:

Shift + Alt + A:

/* Multiline
   comment */

Ctrl + /:

// Single line comment

How to remap / change these shortcuts?

Windows: File → Preferences → Keyboard Shortcuts.

macOS: Code → Preferences → Keyboard Shortcuts.

You can search through the list both by keybindings (key names) and command names.

Shift Alt A does NOT comment things out on Windows, it just wraps text in quotations.

The keyboard shortcut to comment multiple lines in Windows is shift+alt+A.

This one is better in some languages because it toggles "Block Comment". CTRL-/ toggles "Line Comment" which doesn't work in e.g. CSS or HTML.
How can I change this shortcut, I can't seem to find it in File > Preferences > Keyboard Shorcuts?
this is the only one that I was looking for. Simply because it's selection comment not whole line comment. It wraps the selection with /**/ not the whole line. I'm on Windows 10

In my case, Ubuntu, the shortcut is ctrl+shift+A.

in my ubuntu 16 does not work, strange, i can change keys but maybe depends on the file extension?
finally a shoutout for Linux in the 4th answer! works on 20.04
Works on Fedora too! Thank you for your comment, <kbd>shift</kbd>+<kbd>alt</kbd>+<kbd>A</kbd> was not working for me!

You can see all available keybindings on the official documentation.

Here's the relevant bit for OS X:

Key            Command

⌘ + K, ⌘ + C   Add line comment
⌘ + K, ⌘ + U   Remove line comment
⌘ + /          Toggle line comment
⇧ + ⌥ + A      Toggle block comment

You will need to select the lines you want to comment first, and then execute the above shortcut, i.e., ⌘ + / on OS X, and Ctrl / on Windows.

But it doesn't talk about multiline comment.
@AmitGupta: ⌘/ Toggle Line Comment <-- this works for multiline too.
highlight multiple lines and ⌘K then ⌘C or ⌘K then ⌘U will work. ⌘/ also does the same thing. @AmitGupta

Try option 1 first. If it doesn't work for you then try option 2 which is the actual shortcut for Visual Studio Code:

Option 1. Alt / Option + Shift + A

Option 2. While the text is selected hit Ctrl / Cmd+K and then Ctrl / Cmd+C.

As of now (version 1.16.3), you can check all available keyboard shortcuts by going into menu File → Preferences → Keyboard shortcuts. Here you can search for shortcuts related to code comments.

For users who are coming from Sublime Text or likes to have Ctrl+Shift+/, you can make the change from the above mentioned settings panel or simply install the Sublime Text Keymap extension by Microsoft.

As Visual Studio Code has become pretty much the standard editor for almost everything these days, I would say picking option 1 is always helpful.

Seems a bit odd that vscode uses Shift+Alt+A for block comment when line comment is Ctrl+/. ReSharper uses Ctr+Alt+/ and Ctrl+Shift+/ for line and block comment respectively. For vscode one can see that the Shift-Alt-A keys (for block comment) are somewhat easier to press than typical three key combos but it's so non-intuitive as a keyboard shortcut. I configure ReSharper (could also do for regular Visual Studio) to use Ctrl+/ and Ctrl+Shift+/ for line and block comment respectively and vscode to use Ctrl+Shift+/ for block comment so that they are both the same and intuitive.

It should be the same as Microsoft Visual Studio with:

  • Ctrl + up arrow/down arrow: to select
  • Ctrl + K, then Ctrl + C :to comment
  • Ctrl + K, then Ctrl + U :to uncomment

In the new version of Visual Studio Code (version 1.26.1)

Visual Studio Code version

  1. Go to menu File → Preferences → Keyboard Shortcuts
  2. Search for comment, and double-click the existing shortcut 'keybinding`
  3. And press the new keyboard shortcut. In my case, it is Ctrl + Shift + /

You can assign any shortcuts you want.

If you are using Visual Studio Code in a Linux environment, then you can comment multiple lines by either:

Selecting a block of code => then, press Ctrl + Shift + A (Block commenting)

Or, selecting a block of code => then, press Ctrl + / (single-line commenting applied to all selected lines)

For some reason I have trouble with this one. I usually have to press multiple times. CTRL + ALT + A works the best for me.
This one worked fine for me. A nice add-on to this answer is "How to uncomment".
to uncomment use Ctrl + k, Ctrl + U
The link is broken: "Hmm. We’re having trouble finding that site. We can’t connect to the server at visualstudioshortcuts.com."

If your Ctrl+/ isn't working maybe you need to change it to Ctrl+NumPad_Divide.

In Windows, you need to press Ctrl + /. On Mac, you can do ⌘ + / to make multiple comments:

// public function index()
// {
//     $badgeIcon = BadgeIcon::all();
//     return $this->showAll($badgeIcon);
// }

Then if you want to uncomment, then select the lines again and then press Ctrl + / (in Windows) again ⌘ + / (on Mac).
