What proofreading mark is used to switch the order of words in a sentence?

The proofreading mark used to switch the order of words in a sentence is a caret (^) with a curved arrow pointing in the direction of the move.

Here's how it works:

1. Place the caret (^) under the word you want to move.

2. Draw a curved arrow from the caret to the desired position in the sentence.

Example:

Original sentence: The dog chased the cat.

Corrected sentence: The cat chased the dog.

Proofreading mark:

> The ^ cat chased the dog.

This indicates that the word "cat" should be moved to the beginning of the sentence.
