Sublime Text Keyboard Shortcut to Comment Out Lines

John on January 25, 2021

It is possible to quickly comment-out large blocks of code in Sublime Text using keyboard shortcuts, which we will learn to use in this article.

Single-Line Comments Shortcut

To add single-line comments, put the text cursor on the line to comment-out or highlight multiple lines and type CMD + / on Mac, for Linux and Windows use CTRL + /.

The above command will output single-line comments like this in JavaScript:

// $('#foo').click(function() {
// 	$(this).toggleClass('bar');
// });

Block Comment Shortcut

Highlight the block of code to comment out and press CMD + OPT + /  on Mac, for Linux and Windows use CTRL + SHIFT + / to wrap it in a block comment.

The above command will output block comments like this in JavaScript:

/*$('#foo').click(function() {
	$(this).toggleClass('bar');
});*/

Conclusion

If the language you are using does not support single-line comments, Sublime Text will automatically use block commenting.
