How to Select Multiple Messages Based on Message Criteria
To select multiple emails in the current view based on specific criteria, click the downward-pointed triangle (▾) beside the top check box in the Gmail message list toolbar to reveal a list of options. You can then select multiple messages based on criteria:
All: Select all messages in the current view. You can also select all messages by clicking the top check box. Alternatively, use the keyboard shortcut *a. None: Deselect all messages. You can also click the top check box. It will be filled with a check mark (✓) if all messages are currently selected, and with a minus sign (-) when some emails are checked. Alternatively, use the keyboard shortcut *n. Read: Select all emails marked read. Alternatively, use the keyboard shortcut *r. Unread: Select all new and unread messages. Alternatively, use the keyboard shortcut *u. Starred: Select emails marked with a star. Alternatively, use the keyboard shortcut *s. Unstarred: Select all messages not highlighted with a star. Alternatively, use the keyboard shortcut *t.
How to Select Multiple Messages Based on Search Filters
Gmail supports dozens of search filters with options to include or exclude keywords, senders, attachments, message sizes, and date ranges. When you filter based on criteria and then select all the conversations on the page, a new option appears under the message list toolbar: Select all conversations that match this search. If you click the hyperlink, all messages in the search results (not just those on the current page) are selected. Once all messages are selected, unchecking any message on the current page also unselects all hidden emails. The new selection comprises all emails on the current page minus those you unchecked.
