You can select an entire list (or all the contacts from a search that you have done or even all contacts who opened an email or clicked a link) by click the check box in the "column header" area above the table of contact. This will select all contacts in that view, across all page. For example, if you have a list with 500 contacts on it, click that "select all" check box will select all 500 contacts across all 10 pages. Then you can click the Add to Email list or Export buttons to modify or export all 500 selected contacts.
