In Sublime Text, the shortcut Ctrl + Shift + F is used for Find in Files.

Function:

• Find in Files allows you to search for a specific text or pattern across all files in a project or directory.
• This feature enables you to search through multiple files at once, rather than searching one file at a time.

How it Works:

1. Press Ctrl + Shift + F (on Windows/Linux) or Cmd + Shift + F (on macOS).
2. A search bar will appear at the bottom of the Sublime Text editor where you can:
   • Enter the search term or regular expression.
   • Specify the directory or folder where you want to search (optional).
   • Filter by file types (optional).
3. Once you hit Enter, Sublime Text will display a list of all occurrences of the search term in the specified files, allowing you to quickly navigate to them.

Summary:

• Shortcut: Ctrl + Shift + F
• Function: Find in Files (searches across all files in a folder or project).
