How do I select multiple emails in MacBook Air?

To select multiple emails on a MacBook Air, open the Mail app and navigate to your inbox or the folder containing the emails. Hold down the Command (⌘) key while clicking on each email you want to select. If you want to select a contiguous range of emails, click the first email, then hold down the Shift key and click the last email in the range. This will highlight all emails in between as well.
