How can Notepad filter out all specified content?

To filter out all specified contents in Notepad, you can follow these steps:

1. Open Notepad and click on the “Edit” option in the menu bar.
2. Select the “Find” or “Find and Replace” option, or use the shortcut “Ctrl + F” to open the Find dialog box.
3. In the search dialog box, enter the content you want to filter and click the “Find Next” button. Notepad will find the first matching content in the text.
4. If you want to filter out all the matching content, you can click the “Find Next” button multiple times until Notepad highlights all the matching items.
5. If you want to change the filtering criteria, you can modify the content in the search dialog box and click the “Find Next” button again.
6. If you want to cancel the search filter, you can close the search dialog box or click on “Cancel Search” in the “Edit” options.

Please note that Notepad only supports searching within the current text, and cannot search across multiple text files in bulk. If you need to search across multiple files, consider using a different text editor or search tool.
