Proofreading is the art of spotting and removing as many errors as possible from copy before it goes to print.

Everyone has their own notation style for how to delete, insert and format words, letters and paragraphs.

There is, however, a universal proofing style, dictated by the British Standards. Here are a few examples:

The symbol to show you want to turn a capital letter to lowercase.
