In IntelliJ IDEA, Shift + Shift and Ctrl + Shift + F are two very useful shortcut keys with different functions:
1. Shift + Shift：搜索 Everywhere
- Function: This shortcut activates the “Search Everywhere” feature. It allows you to search for almost anything in a unified interface, including files, actions (commands), classes, symbols, settings options, and more.
- Purpose: This feature is useful when you are unsure of the location of a specific element, or want quick access to projects, files, tool windows, menu commands, etc.
- Search scope: This search function covers almost the entire IDE, including project code, menu items, tool windows, settings and more.
2. Ctrl + Shift + F：Find in Files
- Function: This shortcut triggers the “Find in Files” function. It is used to search for specific text or code fragments in the entire project or in a specified directory or file.
- Purpose: This function is very useful when you need to find a specific text string, code fragment, or perform a global search and replace.
- Search scope: This search mainly targets the file content in the project. You can specify the search scope (entire project, current directory, specified range, etc.) and other search conditions (such as case sensitivity, regular expressions, etc.).
Summarize
Shift+Shift(Search Everywhere) : Wider search including files, actions, settings, and more.Ctrl+Shift+F(Find in Files) : Text search focused on the contents of project files.
Both of these features are powerful tools provided by IntelliJ IDEA that can greatly improve your development efficiency. Depending on your specific needs, you can use them flexibly to speed up finding and navigation.
