How to undo and redo an operation
Take this document in WPS Writer as an example.
First, we need to use WPS Writer to open a document. After we edit the document, we can click the Undo bottom in the upper left corner of the page.
We can also use the shortcut key Ctrl+Z to undo the operation.
Click the inverted triangle button on the right side of Undo. We can see the operations that we have just did on the document.
By selecting one of the operations, we can undo as many actions as needed with one click.
If users want to redo the operation that they just undo, click the Redo bottom next to the Undo bottom. Then users can successfully undo the operation.
