Final answer:
To switch from editing the header and footer to the main text in a document, simply click the 'Close Header and Footer' button. No need to select 'Edit Main Text'. Alternatives like 'Read Mode' or Ctrl+E doesn't help in this scenario.
Step-by-step explanation:
When you are editing the header or footer of a document and wish to return to editing the main body text, you can do so by clicking on the Close Header and Footer button. You won't need to select the 'Edit Main Text' option because once you close the header and footer, your cursor will automatically be placed back into the main document, allowing you to continue editing the main text. The option to change the view to 'Read Mode' or utilizing Ctrl+E does not directly relate to the transition from editing headers and footers to the main text.
