Only as a bookmark before adjusting text size, or to copy-to-clipboard. But that's a good point; intercepting those clicks would be annoying to the readers. The handler could distinguish point-clicks from click-drags.
Add doubleclicking to that list, because that's my preferred way of selecting a line of text. Unfortunately a lot of people also doubleclick on links.
I guess there's a lesson here: don't try to chase a higher conversion rate by getting in the way of "savvy" visitors. Still, it's a good idea once you cover all the edge cases.
