Here's, the thing, I have an INI file that looks like this:

Login
username=admin
password=12345

I am using Config::Abstract::Ini to read this section
like this:

    my %Login = $ini_db->get_entry('Login');
[download]

where %Login is a hash that holds those sub keys and their
values.


Now, in the WWW::Mechanize module, I can use these (below)
functions to insert fields to the page, either by using
the hash (%field_values) method or using the @criteria.

    $mech->set_fields( %field_values );
    $mech->set_visible( @criteria );
[download]

Question is, if I can do it like this:

    $mech->set_fields( %Login );
[download]

And it will send the pair key and it's value as defined
in the ini file (?)


Moreover, I know what is a hash and how it looks like,
whats a @criteria? how does it look like?


Thanks.
