IntelliJ shortcut to comment a line

Question

There is a way in WebStorm to comment or uncomment a specific line or selected block of source code with shortcut?
I tried to use CTRL + / but it doesn't work for me.

In MAC `⌥⌘/` to comment only selected text within line, and repeat again for uncomment. — Kanagavelu Sugumar, Aug 10 '21 at 08:20
I was trying to find how I could continue commenting on the next line, and the answer is `Ctrl+Shift+Enter` for those who ended up at this question from Google — Mattwmaster58, Oct 31 '21 at 08:48

Try to use:
Ctrl+/ for Line Comment
or
Ctrl+Shift+/ for Block Comment
or
Set you own keyboard shortcut in Settings from File -> Settings... -> Keymap.
Then search for "comment".

Note: It's the numpad / that works.

Thanks for showing how to change it in the Keymap settings. On thing bugs me: When I comment a line, the cursor jumps to the next line. Is there a way to let the cursor stay on the same line? – John Archer Jun 12 '20 at 08:39

Use CTRL+/, but with the / located on the numpad.

The question remains why commenting with / (the one besides .) does not work (it does not for me, either).

On a Mac with an extra keyboard it is CMD + Numpad's /.
The one on the native Macbook keyboard I did not get to work.

In a Mac replace `Ctrl` with `Cmd`. – Mig82 Jul 02 '20 at 11:47

On Windows with a German keyboard layout the default keyboard shortcut for the comment lines action Ctrl+/ conflicts with the bookmark shortcut Ctrl+7. You need to remove the keyboard shortcut for bookmarks in order to get this to work.

If Ctrl + Shift + / doesn't work , try Ctrl + Shift + Num Pad /. You can check the exact configuration in settings->keymap.

I have an AZERTY keypad in French, so this was the answer for me :

Ctrl + Shift + / on the numpad

Because / out of the numpad was detected as :, even with Caps Lock on.

You can check how the keystrokes are actually detected by IntelliJ in :

On Windows : Settings > Keymap > click on the icon of Magnifying glass with cubes (tooltip is "Find Actions By Shortcut"). In the little tooltip that opens, you stroke the keys and observe the registered results.

On Ubuntu : Settings > Keymap > click on the icon of Keyboard, right next to the search input (tooltip is "Find Actions By Shortcut"). In the little tooltip that opens, you stroke the keys and observe the registered results.

Yeah, this is really annoying! – Abdelkrim Mar 09 '22 at 17:53 — Abdelkrim, Mar 09 '22 at 17:53

Commenting out each line of selected code for Mac users without numpad would have to add a keyboard shortcut:

Navigate to settings: Preferences > Keymap > Main menu > Code
Double click on Comment with Line Comment
Insert your shortcut, for example: cmd + shift + 7 would be interpreted as shift + cmd + 7 but works the same.

You need to activate this option:

'Settings' > 'Keymap' > 'Use national layouts for shortcuts (requires restart)'
