When a "]" appears next to a piece of text, what should the editor do?

In editing contexts, when a "]" appears next to a piece of text, it usually indicates that the text is meant to be moved to a different position, often to the right. This symbol can signal that the text is either intended to be part of a different structure, like being indented or included in a different section. Therefore, the appropriate action for the editor would be to move the text to the right, ensuring that it is placed correctly relative to the overall layout or hierarchical structure of the document. This action helps maintain clarity and organization within the text, aligning it with intended formatting and presentation norms.

The other options do not address the specific action implied by the presence of the bracket. Moving to the left or deleting would not address the structural intent suggested by the "]", while leaving the text as is would neglect the needed adjustment. Thus, moving the text to the right is the action that aligns with the meaning conveyed by the symbol.
