Using AMOS tool for language pack translation
How to find string to translate
And how do I find a component that is not displayed on the drop-down list of components? (assignment)
Thanks in advance.
you are actually looking for mod_assignment. Since Moodle 2.0 we have started slow and long process of correct referencing of Moodle components so from now on, every Moodle plugin should be called as type_name. For activity modules, there is a nasty exception yet that they do not need to have mod_ prefix. Therefore, the name of the file is assignment.php but the component is mod_assignment.
