Fixing the IntelliJ Shortcut: Make Comments Appear at the Current Column

If you're a Java developer using IntelliJ IDEA, you might have run into a frustrating issue when trying to use the ctrl + / shortcut to comment out lines of code. Instead of placing the // at the current column where your cursor is located, IntelliJ might be positioning the comment at the first column. This can be particularly annoying when you are formatting your code and want comments to align properly with the rest of the code. Fortunately, there’s a simple way to fix this issue in the settings. Let’s break it down!

The Problem

When you highlight a line of code and press ctrl + /, you expect it to comment out that exact line at your current indentation level. However, if IntelliJ adds // at the start of the line, it disrupts the formatting you'd like to maintain, making your code harder to read.

Example:

You might have the following line in your code:

[[See Video to Reveal this Text or Code Snippet]]

Using the shortcut results in:

[[See Video to Reveal this Text or Code Snippet]]

Instead of the desired output:

[[See Video to Reveal this Text or Code Snippet]]

The Solution

To resolve this formatting issue, you need to tweak some settings in IntelliJ. Follow these steps to ensure that comments are added precisely where you want them.

Step-by-Step Guide

Access Settings:

Open IntelliJ IDEA and navigate to the menu bar.

Click on File and then choose Settings, or simply press Ctrl + Alt + S to open the settings menu.

Adjust Comment Code Settings:

Go to Editor Code Style Java Code Generation.

Here, you'll find options related to comment placement:

Line comment at first column: Uncheck this option.

Block comment at first column: Uncheck this option.

Modify Wrapping and Braces Settings:

Still within the Code Style for Java, navigate to the Wrapping and Braces section.

Find the setting labeled Keep when reformatting and look for the option Comment at first column. Uncheck this as well.

Wrapping Up

Once you've made these changes, close the settings window and try using the ctrl + / shortcut again while highlighting your code. You should now find that any comments you add will appear at the desired indentation level instead of the first column.

Key Takeaways

Adjust your IntelliJ settings to control comment placement.

Ensure that the options for comments at the first column are unchecked for better formatting.

This adjustment can significantly enhance your coding experience, keeping your code clean and organized.

By following these straightforward steps, you can avoid the hassle of misaligned comments and keep your Java code looking its best. Happy coding!
