How can I make CTRL + / toggle a comment in Visual Studio, as it does with XCode and Eclipse?
12 Answers
Toggle single line comment and toggle block comment commands have been added in VS 2019 for C#
You can change the shortcut for these commands to whatever you want in Tools -> Options -> Environment -> Keyboard, search for Edit.ToggleBlockComment or Edit.ToggleLineComment.

5Oddly, they do not work, not even the defaults, in VS 16.2.2. The error "
The key combination (Ctrl-K, Ctrl-/) is bound to command (Toggle Line Comment) which is not currently available.
" appears at the bottom in the status bar for the default keystrokes, and it doesn't even do that much if you use a custom one. For now, I'll be giving the "Toggle Comment" plugin a try. Aug 19, 2019 at 6:03 -
1This did work for me and if you have VS 2019 is the best solution, actually, is THE solution. VS 12.2.5– NorcinoOct 4, 2019 at 14:44

2This still works in VS 2022. It's insane that this isn't a default yet. Feb 6, 2022 at 6:47
You can't make it toggle without going into either a macro or other VS extension.
However, I always setup VS to comment with Ctrl + / and uncomment to Ctrl + Shift + /
You can customize the keyboard shortcuts by going int the "Tools" menu and selecting "Options". Then select "Keyboard" from the "Environment" branch. From there you can bind the Edit.CommentSelection
and Edit.UncommentSelection
commands to whichever keyboard shortcuts you'd like.

10The secret to making this work was selecting
TextEditor
rather thanglobal
before pressingAssign

If you have ReSharper installed (and using VS without it is/was tedious), you can assign a single key to the command ReSharper.ReSharper_LineComment
.
For instance, I bind the keyboard shortcut Ctrl-K, Ctrl-C
to the command, and then if I use it on a line that is uncommented, it comments it, and if the line is commented, it will uncomment it.

5so to directly answer the original question, assign
CTRL + /
toReSharper.ReSharper_LineComment

You can also create custom shortcuts using above procedure by placing keys inside 'Press shortcuts keys', step by step procedure here: qawithexperts.com/article/c-sharp/… Jul 31, 2021 at 8:41
Apparently, VS2019 has finally introduced alternative keyboard mapping schemes.
They're available at Options -> Environment -> Keyboard
.
I've been looking for a solution for toggle comment shortcut problem and I got a whole surprise package. This is more than I wanted.

The Visual Studio Code mappings are indeed the best way to go about this!– ChrisDec 11, 2022 at 8:03
Ctrl-K and Ctrl-C will comment one or more selected lines.
Ctrl-K and Ctrl-U will uncomment one or more selected lines.
You can get toolbar icons that will do this by adding the "Text Editor" toolbar. In the toolbar area right-click and select "Text Editor" This will add a strip of icon buttons like this:
You can customize this strip by selecting the dropdown at the end of the ribbon:
To edit the keyboard combination go to Tools-Options and select Keyboard under the Environment tree. Here you can change the keys used to trigger the Comment and Uncomment actions:

Edit.CommentSelection doesn't show up in VisualStudio 2015 community edition. Jul 30, 2015 at 14:53
If you're using Resharper, there is an almost identical alternative:
Right Alt+/
By using this single shortcut, you can simply toggle between commenting/uncommenting code.
In Visual Studio Code 2019, this can be done by:
- Enter
hotkeys
in the IDE search field and clickChange hotkeys and keyboard shortcuts
. - In
Show commands containing
, search for and selectEditorContextMenus.CodeWindow.GenerateDocumentationComments
. - Click
Remove
on the right side ofShortcuts for selected command
, wherectrl+/
is currently selected. - In
Show commands containing
, search for and selectEdit.ToggleLineComments
. - Click the
Press shortcut keys
box and pressctrl
+/
. - Click
Assign
to assign the new hotkey.
Note that unbinding the already existing function for ctrl
+ /
is necessary for this to work.

Steps 1-3 are sufficient in latest VS2019, which has
ctrl
+/
as the Global default forEdit.ToggleLineComments

In Visual studio 2022 you also need to install the workload
for ASP.NET and webdevelopment if you want to use the shortcut for Edit.ToggleBlockComment
, as is explained here. If this workload is not installed then pressing CTRL + K will generate an error message in the bottom left of the IDE that says something like The key combination (Ctrl-K, ....) is bound to command (....) which is not currently available.
You can search for the required workload by entering web workload
in the searchbar at the top of the IDE. The workload should pop up as a search suggestion. To install this workload you need 2 GB of free diskspace on your computer. Alternatively you can also install the workload with the Visual studio installer
app. You can easily find and open this app using the search bar of windows. Once the app has started click on Modify
. Then under the tab Workloads select the workload ASP.net and web development
and press Modify
in the bottom right. Visual studio needs to be closed before you can start the workload installation.
When you've installed the workload for webdevelopment in ASP.NET, Javascript/HTML the shortcuts should work. You can change the shortcut of Edit.ToggleBlockComment
to CTRL + /
by going to Tools > Options > Environment > Keyboard
where you can assign the shortcut. You can leave the Use new shortcut in
field on Global
. After that you can use CTRL+/
to both comment as well as uncomment a line of code.
I don't know if it is the same in 2012 but in 2015 you can.
Go to Tools > Options > Environment > Keyboard
Either, find "VisualD.ToggleCommentSelection" or
Search for "comment" and the bottom option should be "VisualD.ToggleCommentSelection"
In visual studio 2022, you can find an extension to toggle blocks of comments. I use Toggle Comment 2022 and it's pretty straight forward. Ctrl+/ comment and uncomment.
