Keyboard shortcut to comment lines in Sublime Text 3

Question

In Sublime Text 2 it was possible to comment out a line or a block of lines with Ctrl+/ and Ctrl+Shift+/. According to the menu Edit > Comment these shortcuts should be valid, but in Sublime Text 3 (build 3047) they no longer seem to work. Does anybody know the right default keyboard shortcuts for Linux and MacOS? Or is it a bug?

Solution 1

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)

Solution 2

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".

Solution 3

This is a keyboard internationalisation issue.

On a standard US QWERTY keyboard, as used in Australia where Sublime Text is made, / is readily available:

This is not the case with many other keyboards. Take for example the German QWERTZ keyboard. One needs to hit SHIFT+7 to get a /. This is why commenting does not work properly on these keyboards.

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.

Solution 4

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 =)

Open the console (View->Show Console) and write this in it: sublime.log_commands(True) and press Ctrl+/ and Ctrl+Shift+/. What do you get in the console output?

Build 3049 has just been released on the dev channel. Try installing that and seeing if the issue has been fixed. And, BTW, on OSX it's Cmd-/, not Ctrl-/.

@dusan the console says command: move_to_group {"group": 6} for Ctrl+Shift+/ and command: focus_group {"group": 6} for Ctrl+/

I think this has been fixed in newer builds. Just dl'ed sublime 3 for Ubuntu 13.10 32 bit and control + / is still working the hot key for comments.

[0x4a6f4672]

Yes, it seems to be a bug, but the workaround does not work satisfactory, at least for Linux (Ubuntu).

[dusan]

If you do sublime.log_commands(True) again and press Ctrl+/ and Ctrl+Shift+/, do you still get the move_to_group and focus_group commands?

[0x4a6f4672]

You are right, you get toggle_comment {"block": false} and toggle_comment {"block": true}. Somehow the block:true command irritated me, it does not seem to work well. The block:false command works as expected.

I would like to note that this also worked on Sublime 3 on Win8 ;) thanks!

toggle have some problems according to css,html,js

[mathiasfk]

Seems like the keyboard is not properly reconized. Strange that the "/"-key works normally when writing but not for the shortcut.

Working now in Linux version

[Oliver Schafeld]

I successfully used this workaround in an Ubuntu VM under Windows, too. [On a German keyboard the forward slash is Shift-7 so Shift-/ is a bit tricky to type anyway. (It is available on the numeric keypad.)]

[Alok Agarwal]

Thanks This really helped

[Tobias Hochgürtel]

Thanks - helped me to understand it complete!

This fix the problem for international keyboards on OSX

[arod]

I wonder how did you came up with the alternate control and keypad_divide?

[f1lt3r]

This seems to work for me on macOS Sierra, however, it does not appear to work with HTML files.

[dotnetCarpenter]

Works great on a danish keyboard on Linux - I guess the OS is not important here only the keyboard. Using Sublime 3.1.1 Build 3176

[Asta86]

Worked on Fedora 29, while ctrl and 7 did not.

[sebastian romero]

This should be the accepted answer as it is not workaround

[Awakened]

what does "args": { "block": false } mean ?
