Create pagination and order according to alphabet

is it possible to create an alphabet pagination? as well as alphabet order of a query post???

I can’t a solution on this based on the regular queries.

I would appreciate any help, thanks in advanced.

UPDATED***

Well since apparently this hard to understand, I will explain myself better.

I’m looking for a way to query post based on the alphabet order that allow me paginate NOT by page but alphabet first letter. In this order I cannot use default order_by = ‘title’ as someBest Answeruggested.

PD: ifyou are going vote down, at least contribute with something, I don’t think that is really hard to understand that more than the 50% of the users of the site don’t use english as first language, so even if we do all our best to help the community we can make mistake sometimes. In this order if you are going to say “Explain yourself better” at least give an opinion of what you understood.

i wrote about something similar recently, maybe it could be helpful to you:

it was based off of my answer to this question:
Group Posts by First Letter of Title

the answer includes both my original posts_where solution and an alphabetical “menu” that for some reason i didn’t write about in my tutorial
