The 2-button mouse changed my life

Seriously. It's not that I wasn't aware that CTRL-click has ever simulated the right-click of the 2-button mouse.
I'm usually filled with glee, in fact, to debunk this myth when my Wintel-touting friends bring it up. It's just that... now that I have the second button, it just occurs to me to use it in places it never occurred to me to CTRL-click. I've been having lots of fun right-clicking everywhere just to see what paradigm-shifting new goodies I can stumble upon. All of us fall into habits in our workflow, and sometimes we miss little tricks that, once we find them,
we can't imagine we could possibly have lived without.

Here's just one example, and I'm hoping you all will post your favorite 'right-click' tips as well: select a word or phrase in Firefox and right-click. Select "Search web for [ ]" to open a new tab with a Google search for that term. In Safari, the option is just "Google Search," and will load the search in the same tab. I'm sure this works in other browsers as well; please testify.
