Wordpress admin: How to add a custom command to the admin post screen

Question

In Wordpress admin, looking at a custom post type list screen

Task: I need to copy the text of the column "Shortcode" (the text is already shown in the list).

Problem: I cannot access the text as the activated plugin "Post Types Order" inhibits overlaying the text by showing me a mouse pointer as part of some means to move the post to some other position (a feature I need)

My idea: When hovering the mouse over a post a number of command-buttons ("Edit", "QuickEdit" and "Trash") show up on the left hand side as can be seen here

An additional command-button "Copy Shortcode" to this set of commands could do the job for me.

Question: How do I add a button to this list right next to "Trash"? (copying to the clipboard using Javascript should be ok)

another alternative: what i did in the past is add another column in the table and add the shortcode text there, from there you can just copy paste — Kevin, Sep 15 '17 at 07:21
here's an hook example for the list https://wordpress.stackexchange.com/questions/253640/adding-custom-columns-to-custom-post-types — Kevin, Sep 15 '17 at 07:23
Thanks for the answer but sorry, it misses my question. I don't want to add a column but a command-button. I added some info to my question. — JohnGalt, Sep 15 '17 at 11:04
The text you wish to copy being the shortcode text where the arrow is? — ProEvilz, Sep 15 '17 at 11:36
In regards to your main question, you ask how to add a button to the list, but do you mean to the edit/quick edit/trash in the **posts** section or to add a button to the list of buttons you want to add to the custom post type section? — ProEvilz, Sep 15 '17 at 11:38
Yes: I want to be able to copy the text in the Shortcode-column by a button in the collection I mentioned, next to "Trash" — JohnGalt, Sep 15 '17 at 11:44

I came up with a more comfortable solution that now fills the column "Shortcode" with hyperlinks of the shortcode text. Thus a simple click on the desired shortcode copies the shortcode-text to the clipboard

Here is the code:

// add column 'Shortcode' in admin 'Layouts' list page
    // filter & action
    add_filter( 'manage_posts_columns', 'jg_add_id_column', 5 );
    add_action( 'manage_posts_custom_column', 'jg_id_column_content', 5, 2 );

    //add_filter( 'manage_et_pb_section_columns', 'jg_add_id_column', 5 );
    //add_action( 'manage_et_pb_section_custom_column', 'jg_id_column_content', 5, 2 );

    // display column title
    function jg_add_id_column( $columns ) {
      if( get_post_type( $post_id ) == 'et_pb_layout') {
         $columns['jg_id'] = 'Shortcode';
      }
      return $columns;
    }

    // display column value = shortcode-string
    function jg_id_column_content( $column, $id ) {
      if( get_post_type( $post_id ) == 'et_pb_layout') {
        if( 'jg_id' == $column ) {
          echo '<a id="myButton',$id, '" name="myButton',$id, '" class="myButtonClass">[showmodule id="', $id, '"]</a>';
        }
      }
    }

The Javascript for copying the text to the clipboard was created according to the stackoverflow.com post 'Click button copy to clipboard using jQuery'. Thanks for the helpful comments.

this is what i'm referring to, add another column for the shortcode :) add another column and the contents for that column would be to create the shortcode for each row, anyways nice job — Kevin, Sep 17 '17 at 05:10
We have had a misunderstanding there. I already had the column in there but just couldn't mark and copy the text as the "Post Types Order"-plugin was overlaying it. That's why I was just looking for a means to add a custom command. As I am not a Wordpress expert It took me two days of reading (time well spent) to come up with a plugin that works well. Now I want learn how to upload a plugin so that the community can make use of it, too. — JohnGalt, Sep 17 '17 at 09:14
