I have been using Calibre for a while, love it, but am still very much a newbie. Sorry if this is a stupid question! Once I get a couple hundred of books into Calibre there is alot of scrolling to get from the top of the list of books to the bottom. (yeah, I know, I'm a whiner!

) Is there a way to click a letter and have calibre jump down to, say, N authors? Then click another letter and have it jump back up to G? I've never changed the way my Calibre looks, and honestly dont' even know if it is possible, so I don't even know if this is a hidden feature or not.
Thanks for the help!
