The Query Type "From Specific Post" is useful to build a static list filled by posts that do not have real dynamic management. With it, you can generate a list of all the posts you want.
With this query you can choose:
order by Post ID | Post Author | Title | Date | Last Modified Date | Parent ID | Random | Comment Count | Menu Order | Meta Value NUM | Meta Value DATE. If you select "Meta Value" you must choose the Meta Field;
order ascending or descending.
