How to comment out multiple lines at once in Notepad++?

Question

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?

Solution 1

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.

Solution 2

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.

Solution 3

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 the shortcut aren't working to (un)comment: delete langs.xml and try again.

I have created a .html file and executing the command results in <!-- -->, but nothing happens in a .scala file

CTRL + SHIFT + Q results in /* */ in a .java file

These are the different comments for different languages. Here is a list of supported languages natively in Notepad++: en.wikipedia.org/wiki/Notepad%2B%2B#Programming_languages

The ALT + LMC and subsequently // works in .scala as well. To uncomment: ALT + LMC and subsequently two times DEL

So how do you uncomment in HTML?

[Pacerier]

Select multiply lines and Ctrl+Q is faster than multiline select and //

[Pacerier]

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.

Verified that CTRL+K works as well to comment out in Notepad++

"This will toggle comments on and off" as VitaminYes wrote. If you want to re-commment the commented lines, see @john-robertson 's response superuser.com/a/916881/342669

user Ctrl+Shift+K to uncomment

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.

<kbd>Ctrl</kbd>+<kbd>Q</kbd> 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.
