Select All transactions displayed in the transaction list view
You can now select all the transactions in the transaction list view with a simple tap to the Bulk Select box beneath the filters.

When the Bulk Select box is checked, all the transactions' boxes will be checked.

You may deselect any individual transactions by simply tapping the box next to them.
Next, choose the action to apply to all of the remaining selected transactions.
Hovering over the action buttons shows what they do. Click the one you wish to do.
From left to right, are Archive, Unarchive, Mark as read, Mark as unread, Download (coming soon), and Export headers.
A confirmation window will ask if you are sure you want to apply the action to multiple items.

Once confirmed, a confirmation will flash in the upper right corner of the screen.
If some of the transactions did not need to be actioned because they were already in that state, then a yellow confirmation will advise how many out of the total were actioned.

Another handy tool is the drop down menu/arrow to the right of the Bulk Select box. Tapping the down arrow gives a choice of Unread or Read.

Choosing one will select all the transactions of that status for further actions.
