I hope to clarify this with any BeBook owner, please (I know I'm posting this in several threads, but I'm looking for an answer as I was thinking on buying the Cybook, but I'm now beginning to be interested on the BeBook

)
Is any of these two formats
.lit or
.prc/.mobi actually supported and does any of them support
bookmarks (in several different books simultaneously),
search function within a book (search for a word or a group of words) and
dictionary lookup (without leaving the current book)?
Any answer will be extremely apreciated

Thanks to you all and I hope I'm not being too annoying...
EDIT:
Ok, after some more reading I understand that
bookmarks is a
no on
.prc/.mobi - but what about
.lit (though it seems this format is not so well implemented on the BeBook - or am I wrong assuming this?)?
Also, I understand that the
dictionary lookup is supported for
.prc/.mobi but in a convoluted way... is this a fact? And, again, what about
.lit?
And now I'm thinking that a search function is also something not implemented... any help here?
I must've been spoiled by my HX700 where all these functions exist and are well implemented both for .lit and .prc...
