Right there, in Manage authors. You can edit the author_sort values, as "master" values.

1) The author is already there.
2) Which cell I have to click?
3) Using the F2 key results only in a less light to completely darkening screen.

F2 is the default single value metadata edit shortcut key. The highlighted cell should start looking like this (you can also double-click the cell):


Since there is no author_sort cell, calibre auto-calculates the author_sort value, using the value in Manage Authors.

Yes and No!

Correct Author sort shows red.

Because according to the Manage Authors rules, it doesn't match, I guess.

Is that what you mean: Whether I edit a book by an author in Edit metadata individually or more books with Edit metadata in bulk edit in relation to the writing of the author: Manage Authors page does not accept the changes. Yes or No!?

Edit Metadata uses whatever you type in. There is an arrow button pointing from the Author to the Author Sort, which will set it based on the rules in Manage Authors.

What is to reset or do I want to reset anything at all?

All I wanted is that in Edit Metadata the Author sort entry shows the same upper/lower case than the Author(s) entry.

And the only way to realize that is: Recalculate all author sort values in Manage Authors

In Bulk Edit Metadata, you can select "Automatically set author sort" which will use the values saved in Manage Authors.

Manage Authors is a book full of rules, what authors should look like.
Like the way The Chicago Manual of Style is a book full of the rules of writing... but if you put the ebook on your ereader, it doesn't change all your books to match the rules.

Edit Metadata says what the author/author_sort is for any particular book. Red indicates that you should take a second look, since it doesn't match Manage Authors.
