How to get the article/blog entry title to appear in browser title bar?

Hey there,

I’ve browsed through the Template Tags/wp title page in the Codex and, unless I’m missing something, I couldn’t find the answer to what I’m looking for on there.

Any how, I would like for the subject line of the post to appear in the browser title line. What’s the tag I would use for this?

I’ve noticed that not having the article title included in the title line has been killing my search engine listings and traffic therein. Also, on a somewhat related note, is it possible to have a search engine pull from a post’s excerpt to use as a description rather than whatever random text it first encounters in a crawl?

Thanks.
