For example, you’re on a Lead’s page and want to search for an account. Typing “accounts” in the search box shows the dropdown box. Then choose the option to limit your search to Accounts (1).
It’s easier finding a contact than it ever was. Enter a first or last name, or both, also the account name. Contacts matching the search terms and relate the specified account are returned.
On account record page, clicking on Actions dropdown menu will show you the View Account Hierarchy action. If you customized the Salesforce1 and Lightning Experience Actions of the account page layout before Spring ’17, add the action to your account page layout.
