>>> NOWHERE on that page did I find a place where I could type in the simple keyword "bossa".

Correct. There isn't a filter to type a word and restrict the styles displayed to the searched word. Yes, that would be a good feature, and yes, some other windows in BB have it, but NO, the stylepicker doesn't have it, and we're very sorry about that. Adding a filter is something we plan to add.

What the stylepicker does have to find bossas is this:
- click on the "Latin" category. You now see a list of latin styles, and most of them are bossas up top. Press the search button, and type bossa if you want to find one, and it will jump to the next one in the list.

Have Fun!
