Unlock IntelliJ IDEA: 14 Hidden Shortcuts to Supercharge Your Coding

1. Avoid Over‑Customizing Shortcuts

IntelliJ IDEA leaves many actions without default shortcuts, so developers often create their own. Over‑customization can cause conflicts with other applications, be hard to remember, and break when sharing the IDE with teammates.

Rebuild Project

Compare With Branch

Use Ctrl+Shift+A to search for any action by name, e.g., type "Rebuild Project" and press Enter to execute it directly.

2. Use Ctrl+Alt+H Carefully

Ctrl+Alt+H shows the call hierarchy, but it only displays the depth of calls, not the exact number of invocations. When a method is called multiple times, the hierarchy can be misleading.

public class TestService {
    public void test1() {
        System.out.println("aa");
    }
    public void test2() {
        test1();
    }
    public void test3() {
        test1(); // called twice
        test1();
    }
}

For precise callers, use Alt+F7 instead.

3. Common Questions About Ctrl+Alt+H

Jump to Source

After invoking Ctrl+Alt+H, select a call with the arrow keys and press F4 to open the source file.

Return to Hierarchy View

Press Alt+8 to go back to the Call Hierarchy window.

4. Quickly Find Controller Methods

When a project contains many controllers, press Ctrl+Alt+Shift+N and type part of the URL (e.g., "/bill") to locate the corresponding method instantly.

5. Bookmark Key Business Methods

Bookmarks let you collect important methods in one place for easy navigation.

Steps:

Press Ctrl+F12 to list all methods in the class and type the method name (e.g., test1).

Press F11 to add the method to bookmarks.

Press Shift+F11 to open the bookmark list.

Press Ctrl+Enter to rename the bookmark.

6. Keep Only One Tab

Configure the IDE to use a single editor tab: open Settings with Ctrl+Shift+A, search for "Editor Tabs", set Placement to None . Use Ctrl+E to view recent files.

7. Read Long or Smelly Code Efficiently

Create Custom Code Folding Blocks : Place the cursor inside a block and press Ctrl+Shift+. Use Ctrl+- to collapse.

Brace Matching : Position the cursor on a brace and press Ctrl+] or Ctrl+[ to jump to the matching brace.

Highlight Variable Usage : Ctrl+Shift+F7 highlights all usages; press F3 to navigate to the next occurrence.

Quick Definition Popup : Ctrl+Shift+I shows the definition of the symbol under the cursor in a popup.

Press Esc to close the popup.

8. Jump to Superclass or Interface

When editing an implementation method, press Ctrl+U to navigate to the corresponding method in the super‑type.

public interface UserService {
    void test1();
}

public class UserServiceImpl implements UserService {
    @Override
    public void test1() {
        // implementation
    }
}

9. Undo/Redo Shortcut

Use Ctrl+Z to undo recent changes and Ctrl+Shift+Z to redo them.

10. Switch Color Scheme Quickly

Press Ctrl+` (Ctrl plus back‑tick), select "Color Scheme", and press Enter to open the theme selector.
