How to search only in currently open files in vscode?

Searching for the currently open file in Visual Studio Code (VSCode) is an intuitive process. Here are the detailed steps:

1. Open the File: First, ensure that the file you want to search is already open.

2. Open the Search Function: You can open the search function for the current document using the shortcut Ctrl+F (on Windows) or Cmd+F (on Mac). This will open a small search bar at the top of the editor.

3. Enter Search Content: Enter the search term in the pop-up search box. The search bar typically includes options such as case sensitivity, whole-word matching, or using regular expressions. You can select these options as needed.

4. View Results: After entering the search term, VSCode will automatically highlight all matching results in the current file. You can navigate between matches using the up and down arrow buttons next to the search bar.

Example

Suppose you are working on a project that includes a file named index.js. You need to quickly find all instances where the variable userId is used.

1. You first ensure that the index.js file is already open in VSCode.

2. You press Ctrl+F to open the search bar.

3. You enter userId in the search box.

4. You find that userId is mentioned several times in the file. By clicking the down arrow next to the search bar, you review each instance one by one to understand and examine the context of userId usage.

Using this feature, you can efficiently search within a single file without manually browsing the entire file or using global search, which might return results from other unrelated files in the project. This makes it very convenient for local code review or modification.
