You're absolutely right — IntelliJ's autocomplete (IntelliSense) and refactoring tools are extremely powerful and reliable for navigating and updating variable names, method signatures, class references, and more. Manually searching or editing names often increases the risk of introducing errors, especially in large codebases.

Here’s why using IntelliJ's features is a best practice:

• Refactoring tools (Shift+F6 for renaming): They ensure all references are updated correctly, including usages in comments, strings, and across different files.

• Autocomplete: Speeds up development, reduces typos, and helps discover methods or classes you might overlook.

• Find Usages (Alt+F7): Lets you instantly see where a symbol is used, making it easier to judge the impact of changes.

Unless you're doing something IntelliJ can’t infer (like runtime-dependent variable usage), relying on these features is both safer and faster.
