Practical IntelliJ IDEA Tips and Shortcuts for Efficient Coding

IntelliJ IDEA offers a Presentation Mode (Alt+V → Enter Presentation Mode) that maximizes the IDE window and focuses on a single class, allowing distraction‑free coding; you can exit with Alt+V → Exit Presentation Mode.

When editing JSON strings, use the Inject Language feature (Alt+Enter on a string, select "Inject language or reference", then choose JSON) to automatically escape double quotes and edit the JSON fragment directly, exiting with Ctrl+F4.

For quickly locating files, use Ctrl+E for recent files, Ctrl+N or Ctrl+Shift+N for class and file navigation, and Alt+1 to focus the Project view, then Ctrl+Shift+←/→ to adjust the splitter.

Ctrl+Shift+Enter adds missing braces or completes statements, while Ctrl+W followed by repeated Alt+J selects multiple occurrences of a text (e.g., "rabbitTemplate") for batch editing.

Hide the navigation bar with Alt+V → Navigation Bar, and toggle its visibility with Alt+Home; press Esc to hide the temporary bar.

To locate the current class in the Project view, press Alt+F1, choose Project, and press Enter; return to the editor with Esc or F4.

Search symbols with Ctrl+Shift+Alt+N, and use Ctrl+Shift+N combined with "/" to search directories.

Generate conditional checks (e.g., not‑null) automatically by typing the condition after a variable and pressing Enter.

Find code patterns such as try‑catch blocks lacking exception handling using Structural Search: invoke Ctrl+Shift+A, type "Search Structurally", edit the template to set the maximum count for CatchStatement to 1, and run the search.
