如何取消只读模式

To cancel the read-only mode, you can follow these steps:

1. Open the file or document that is currently in read-only mode.
2. Look for an option or button that allows you to edit the document.
3. If there is no obvious option to edit, try saving the document with a new name or in a different location.
4. Close the document and reopen it to see if it is now editable.

If the file is still in read-only mode, you may need to check the file properties or permissions to ensure that you have the necessary access rights to edit the document.
