Boost Your Productivity with Essential IntelliJ IDEA Shortcuts & Plugins

Introduction

IntelliJ IDEA is a powerful integrated development environment (IDE) widely used for Java, Kotlin, Python, JavaScript and many other languages. Its intelligent code completion, robust debugging tools, and rich plugin ecosystem make it a top choice for developers.

Common Usage Tips

1. Keyboard shortcuts to improve efficiency

IntelliJ IDEA provides many shortcuts that can dramatically speed up work: Ctrl + N: Quickly search for a class name. Ctrl + Shift + N: Quickly search for a file. Ctrl + Alt + L: Reformat code. Ctrl + Shift + F10: Run the current file or test. Ctrl + E: View recently opened files. Ctrl + Shift + A: Find and execute any action, also searchable for shortcuts. Alt + Enter: Show quick‑fix suggestions or apply intelligent recommendations.

2. Multi‑cursor editing

Press Alt (Windows) or Option (Mac) to add multiple cursors, allowing simultaneous edits in several places—useful for bulk renaming or editing repeated code patterns.

3. Code auto‑completion

IntelliJ’s completion is context‑aware. Type a fragment and press Ctrl + Space to trigger suggestions for methods, variables, or class names, reducing manual typing.

4. Find Action for quick commands

If you forget a shortcut, use Ctrl + Shift + A (Windows) or Cmd + Shift + A (Mac) to search and execute any action, such as opening files, running tests, or changing settings.

5. Integrated version control (VCS)

IntelliJ supports Git, SVN and other VCSs directly within the IDE.

View branches: Press Alt + 9 to open the Git tool window.

Switch branches: Ctrl + Shift + [ (Windows) or Cmd + Shift + [ (Mac) quickly changes the current branch.

6. Quick documentation lookup

Press Ctrl + Q (Windows/Linux) or F1 (Mac) to view documentation for the symbol under the cursor, helping you understand method signatures and class details instantly.

Recommended Plugins

1. Lombok

Lombok generates getters, setters, toString, equals and other boilerplate code via annotations. After installing the Lombok plugin, IntelliJ automatically recognizes Lombok annotations, eliminating compilation warnings for missing methods.

Installation: File → Settings → Plugins, search for “Lombok” and install.

2. Rainbow Brackets

This plugin colors matching parentheses, brackets and braces differently, making it easier to see code block boundaries, especially in deeply nested code.

Installation: File → Settings → Plugins, search for “Rainbow Brackets”.

3. Key Promoter X

Key Promoter X shows a popup with the keyboard shortcut whenever you invoke an action via the mouse or menu, helping you learn and adopt more shortcuts.

Installation: File → Settings → Plugins, search for “Key Promoter X”.

4. CheckStyle-IDEA

CheckStyle-IDEA checks Java code against style guidelines defined by your team, ensuring consistent formatting and reducing style‑related issues.

Installation: File → Settings → Plugins, search for “CheckStyle-IDEA”.

5. GitToolBox

GitToolBox adds extra Git features such as commit history view, file status indicators, and automatic repository updates, streamlining Git workflow inside the IDE.

Installation: File → Settings → Plugins, search for “GitToolBox”.

6. String Manipulation

String Manipulation provides utilities for transforming strings—uppercase, lowercase, reverse, escape/unescape, etc.—facilitating quick text processing.

Installation: File → Settings → Plugins, search for “String Manipulation”.

Conclusion

IntelliJ IDEA is a feature‑rich, extensible development tool. By mastering essential shortcuts, leveraging multi‑cursor editing, using code completion, employing Find Action, and integrating VCS, you can significantly boost productivity. Adding the recommended plugins further enhances the development experience and streamlines daily workflows.
