In Eclipse it is possible to comment out multiple lines at once by selecting them and executing CTRL + /:

// helloworld

Is this possible in Notepad++ as well instead of typing /+/ in front of each individual line?

Select desired lines and then press CTRL+Q. This will toggle comments on and off.

Also, I've just recently become a fan of ALT + Left Mouse Click to select multiple lines and just manually comment those lines with //.

I've found the ALT + Left Mouse Click trick to work well with Visual Studio, JetBrain products, Notepad++ but not Eclipse.

    The ALT + LMC and subsequently // works in .scala as well. To uncomment: ALT + LMC and subsequently two times DEL – 030 Jul 30 '14 at 20:01

    Select multiply lines and Ctrl+Q is faster than multiline select and // – Pacerier Jun 30 '15 at 02:57

    "This will toggle comments on and off" as VitaminYes wrote. If you want to re-commment the commented lines, see @john-robertson 's response http://superuser.com/a/916881/342669 – malarres Sep 16 '15 at 14:20

    For the people, with who CTRL+Qdidn't work, you have to choose the lanuage of your file from the language menu, otherwise notepad++ will not know what is the comment type you want. – Mohammed Noureldin Feb 07 '17 at 18:44
  • Ctrl+Q does not quite work as expected, though. If there is already a comment in there, the comment is un-commented. For example, select a bunch of C++ code with one of those selected lines being // This is amazing code!. Now that line will be converted to This is amazing code!. The feature is "doing what it says on the tin", just not what was expected! Personally, I'd expect that if >50% of selected lines were not commented then comment them all, and vice versa. – AlainD Nov 16 '20 at 23:03

Also CTRL+K works well in Notepad++ to comment. If you had existing comments in a long block you are commenting, CTRL+Q will uncomment your actual comments, where CTRL+K just add another level of // in front. CTRL+SHIFT+K removes a single line comment from the selection.

  • This is a Ctrl-Q bug actually. If there are half commented lines and half uncommented lines, Ctrl-Q should comment them all, then uncomment them all, then comment them all again. – Pacerier Jun 30 '15 at 03:09

    Verified that CTRL+K works as well to comment out in Notepad++ – 030 Jul 18 '15 at 18:56

In notepad++ I believe that the shortcut is CTRL+Q for commenting the code.

You can go to Settings > Shortcut Mapper to change this to match your preference.

The default for a block comment is CTRL+SHIFT+Q. So you can highlight the block of code then use this shortcut.

If you prefer only using the mouse, install the "Customize Toolbar" plugin from the plugin manager, and add "Single Line Comment" and "Single Line Uncomment" buttons.

An alternative is to use a macro with a custom shortcut (CTRL+Q didn't work on javascript inside a .html document)

The trick works for a single line comment only.

Create the macro :

  1. Macro > Start recording

  2. place the cursor in your doc and type: //

  3. Macro > Stop recording

  4. Macro > Save
  5. Give a name and select your prefered keyboard shortcut.

To quickly comment a line :

Place the cursor at the beginning of the line to comment and press the shortcut you defined for the macro.
