What will happen if you leave the replace with box empty in a find and replace action?

When using the find and replace action, leaving the "replace with" box empty indicates that you wish to remove the instance of whatever is found during the "find" operation. Therefore, if you find a tag or a value without specifying what to replace it with, it results in that tag being deleted. The action essentially tells the system to look for the specified item and eliminate it from the context, thereby removing the tag from its location.

So the correct understanding aligns with the behavior in data management systems, where an empty replacement means that the selected content is omitted, confirming that the tag will indeed be removed.
