With bookmarks you need only type an alt-b -- it toggles.the bookmark.

  What you want here is to get back to a sentence.  I'd highlight it instead.

  At the beginning of a sentence, press the 5-way center down and 

then continue to the right or down (or even across a page) and when you get to the end of the sentence or partial paragraph you want, press the 5-way button down again.

  That creates a highlight (underlined) and is faster for me than 

doing it on my NookColor with my finger, which invariably gets the wrong letter or row.

  When you want to find your highlight (or note), press the Menu 

button and go down to "View my Notes & Marks" and you'll get a list of the ones you made in the order they're in the book, with context and a link to the annotation.

  That's a pretty good solution.  You'll also find a personal 

private,password-protected annotations webpage of all your notes for a book, on the Amazon servers. See how at bit.ly/webknotes1 as it's a really useful feature.

  If you don't want your annotations backed up to your area on their 

servers, just go to the Kindle's Home screen and use the Menu button to get Settings and turn off Annotations Backup.

APOLOGIES. I have no idea how to edit on this. The first one I did w/normal word wrapping while writing didn't wrap when I was reading and most of it was off the screen. This final result is very odd. :-)
