Can web analytic tools track user’s behavior across tabs?

I'm curious about logging user actions across multiple tabs; is a user's actions across multiple tabs within a browser trackable? So from user's point of view is there an additional element of privacy in opening a new window as opposed to opening a new tab? i.e. can a website open in TAB 'A' use analytics tools to track a user's clicks in TAB 'B'?

UPDATE Yes of course I realize that if I go visit Amazon from 2 separate tabs they would know that I'm the same visitor because cookies are on; but if I'm on Amazon, and then go and type in a Barnes and Nobles URL in another tab say to price compare, can Amazon know that I went to visit Barnes and Nobles because it is in another tab in same browser? So that's to say I'm not going to B&N by clicking on any link the Amazon site itself (which they can monitor) but I'm keying in B&N on the 2nd tab and doing stuff there - can AMZ track my activity on B&N?
