Keyboard shortcut to comment lines in Sublime Text 3

It seems a bug: http://www.sublimetext.com/forum/viewtopic.php?f=3&t=11157&start=0

As a workaround, go to Preferences->Key Bindings - User and add these keybindings (if you're using Linux):

{ "keys": ["ctrl+7"], "command": "toggle_comment", "args": { "block": false } },
{ "keys": ["ctrl+shift+7"], "command": "toggle_comment", "args": { "block": true } }

Update: This also works on Windows 8 (see @Sosi's comment)

You can add the following lines to Preferences / Key Bindings - User:

{ "keys": ["control+keypad_divide"],"command": "toggle_comment", "args": {"block": false} }, 
{ "keys": ["shift+control+keypad_divide"],"command": "toggle_comment", "args": {"block": true}}

This is how I sorted the problem out - replacing "ctrl" with "control" and "/" with "keypad_divide".

This is a keyboard internationalisation issue.

Changing the user keybindings to those listed below, will work for the German QWERTZ keyboard.

{ "keys": ["ctrl+7"], "command": "toggle_comment", "args": { "block": false } },
{ "keys": ["ctrl+shift+7"], "command": "toggle_comment", "args": { "block": true } }

If the problems are occurring with still a different keyboard layout, change the keybindings accordingly.

U can fix this bug by:

[
   { "keys": ["ctrl+keypad_divide"], "command": "toggle_comment", "args": { "block": false } },
   { "keys": ["ctrl+shift+keypad_divide"], "command": "toggle_comment", "args": { "block": true } },
]

it allow to comment with CTRL+/ and CTRL+SHIFT+/ and u can use / on keypad =)

This worked for me.

cmd + /

I'm on Mac OS X El Capitan. Sublime Text 3 (stable build 3114).

I'm under Linux too. For me, it only works when I press CTRL+SHIFT+/, and it's like a single comment, not a block comment. The reason is to acceed the / character, I have to press SHIFT, if I do not, sublime text detects that I pressed CTRL + :.

Here it is my solution to get back normal preferences. Write in Key Bindings - User :

{ "keys": ["ctrl+:"], "command": "toggle_comment", "args": { "block": false } }, { "keys": ["ctrl+shift+:"], "command": "toggle_comment", "args": { "block": true } }

On OSX Yosemite, I fixed this by going System Preferences, Keyboard, then Shortcuts. Under App Shortcuts, disable Show Help menu which was bound to CMD+SHIFT+7.

My keyboard layout is Norwegian, with English as the OS language.

It's simpler than you think press cmd + / in mac.

For Brazilian ABNT Keyboards you do Ctrl + ; to comment and repeat it to remove the comment.

In my notebook keyboard, a ABNT 2, I can use the CTRL+; shortcut as the default comment action for blocks and lines. The same shortcut to uncomment.

Use Ctrl + / for single line comment and Ctrl + Alt + / for block or multiline comments.

i am ubuntu 18 with sublime text 3.2

CTR + /

On MAC instead of shift use ALT like this CMD + ALT + /

I prefer pressing Ctrl + / to (un)comment the current line. Plus, I want the cursor to move down one line, thus this way I can (un)comment several lines easily. If you install the "Chain of Command" plugin, you can combine these two operations:

[
    { 
        "keys": ["ctrl+keypad_divide"], 
        "command": "chain",
        "args": {
            "commands": [
                ["toggle_comment", { "block": false }],
                ["move", {"by": "lines", "forward": true}]
            ]
        }
    }
]

Make sure the file is a recognized type. I had a yaml file open (without the .yaml file extension) and Sublime Text recognized it as Plain Text. Plain Text has no comment method. Switching the file type to YAML made the comment shortcut work.

Had the same issue. Check with sublime.log_input(True) command on the console to see what keys are being detected with the CTRL+/ and SHIFT+CTRL+/ shorcuts. Then replace the shortcuts with those. (Changing / for keypad_divide worked for me)

For me, on Mac OS Sierra :

{ "keys": ["super+forward_slash"], "command": "toggle_comment", "args": { "block": true } }, { "keys": ["super+alt+:"], "command": "toggle_comment", "args": { "block": false } },

Sublime 3 for Windows: Add comment tags -> CTRL + SHIFT + ; The whole line becomes a comment line -> CTRL + ;

If the shortcut ctrl+?, ctrl+shift+? or ctrl+/ is not working, try switching to another, like ctrl+1, ctrl+shift+1, it worked for me.

{ "keys": ["ctrl+1"], "command": "toggle_comment", "args": { "block": false } }, { "keys": ["ctrl+shift+1"], "command": "toggle_comment", "args": { "block": true } }

On my mac the shortcut is ⌘cmd + / which makes multi line comment but as single lines:

// if ($username && $password) {
//  echo "You are good to go";
// } else {
//  echo "Fields cannot be blank";
// }

OR

⌥ alt + ⌘cmd + / and it's result is overall comment, from beggining of the selection to the end.

/*
if ($username && $password) {
    echo "You are good to go";
} else {
    echo "Fields cannot be blank";
}
*/

In case anyone has had further issues with Sublime 3 on Windows 7, the above suggestions all did not work for me. However, when I 1 - reran the app as administrator and 2 - highlighted, and chose Edit -> Comment -> toggle comment, afterwards I was able to use a user preferences set keybinding to toggle comments. I don't really have an explanation for why it worked, except that it did.

Open sublime Text 3 and go to Preferences menu and the click on Key Bindings then paste this code to make a comment shortcut with CTRL+D.

[{ "keys": ["ctrl+d"],"command": "toggle_comment", "args": {"block": false}},]

then save it. now you can use shortcut.

On windows, use Ctrl + Shift + ?. You will be able to comment the HTML.

This worked just fine for me on Win 10:

    [{ "keys": ["ctrl+7"], "command": "toggle_comment", "args": { "block": false } },
{ "keys": ["ctrl+shift+7"], "command": "toggle_comment", "args": { "block": true } }
]

note that "[ ]" are nesassary and it will give you an error if you miss them.

I might be late to the party but as of my build 3176 it appears the bug is fixed. Just used Ctrl+T and it worked for a CSS file (Kubuntu 18.10)

In Windows use ctrl + shift + : to comment for Python.
