JetBrains IntelliJ keyboard shortcut to collapse all methods
Navigating large codebases can feel like traversing a dense forest. Finding your way through nested classes, sprawling methods, and endless lines of code can be a daunting task. But what if you could clear the underbrush with a single keystroke, revealing the structure of the forest at a glance? In IntelliJ IDEA, the powerful IDE from JetBrains, this is entirely possible thanks to the “collapse all methods” keyboard shortcut. Mastering this shortcut will significantly boost your coding efficiency, allowing you to focus on the logic of your code rather than getting lost in the details.
The Power of Collapsing Code
Imagine opening a file with thousands of lines of code. Instead of being overwhelmed by a wall of text, you can instantly collapse all methods, leaving only class and interface declarations visible. This bird’s-eye view provides a clear understanding of the overall structure, allowing you to quickly locate the specific section you need to work on. This is particularly useful when working with unfamiliar codebases or when revisiting older projects.
Collapsing code also helps improve focus and concentration. By hiding unnecessary details, you can minimize distractions and concentrate on the specific area you’re working on. It’s like decluttering your workspace, but for your code.
This feature significantly impacts code comprehension, especially in object-oriented programming. By viewing the class structure at a high level, you can better grasp the relationships between different components and understand how they interact.
IntelliJ IDEA: Your Code Navigation Ally
IntelliJ IDEA, renowned for its intelligent code assistance and robust features, offers a seamless way to collapse all methods. This IDE is designed to streamline your workflow and boost productivity. With its intuitive interface and powerful shortcuts, navigating and understanding complex code becomes significantly easier.
Beyond just collapsing methods, IntelliJ IDEA provides a suite of tools to enhance code navigation. Features like “Go to Class,” “Find Usages,” and “Structure View” all contribute to a smoother coding experience.
For developers working with Java, Kotlin, Scala, and other languages, IntelliJ IDEA provides a tailored environment optimized for each language’s specific nuances.
Mastering the Collapse All Methods Shortcut
The shortcut to collapse all methods in IntelliJ IDEA varies slightly depending on your operating system:
- Windows/Linux: Ctrl+Shift+Minus
- macOS: Command+Shift+Minus
Memorizing this simple shortcut can drastically improve your navigation speed. It’s a small investment that pays off significantly in the long run, especially when dealing with extensive projects. This shortcut isn’t just about collapsing methods; it’s about gaining control over your codebase and navigating it with ease.
Once collapsed, you can selectively expand methods as needed by clicking on the plus icon next to the method declaration. This allows you to drill down into specific areas while maintaining a clear overview of the overall structure.
Beyond Collapsing: Other Useful Shortcuts
IntelliJ IDEA offers a wealth of keyboard shortcuts that can significantly boost your productivity. Here are a few more essential shortcuts to add to your arsenal:
- Ctrl+N (Windows/Linux) / Command+O (macOS): Navigate to Class
- Ctrl+Shift+N (Windows/Linux) / Command+Shift+O (macOS): Navigate to File
- Ctrl+F12 (Windows/Linux) / Command+F12 (macOS): File Structure
Learning these shortcuts can dramatically reduce the time you spend searching for files and classes, allowing you to focus on writing code. Investing time in mastering these shortcuts is an investment in your efficiency as a developer.

Question & Answer :
I’m working on some legacy code that has a class that is 10,000+ lines of code and has 100s of methods. Is there a shortcut for any JetBrains IDE (since the shortcut would likely be shared across all of them) to collapse all the methods / functions so that only the method signatures are shown?
Something like this:
public String myMethod(String arg1, int arg2){...} public String mySecondMethod(String arg1, int arg2){...}
You may take a look at IntelliJ code folding shortcuts.
- On Windows / Linux do: Ctrl+Shift+-
- On macOS use Command+Shift+-
- To unfold again do Ctrl+Shift++ or Command+Shift++ respectively.
- To unfold only a single method on Windows, use Ctrl+Alt+Plus.
