Adding this snippet to functions.php your topic WordPress will add a selection menu (custom media_buttons) with an automatically generated list of your short numbers.

And here is the code snippet for WordPress

add_action('media_buttons','add_sc_select',11);
function add_sc_select(){
    global $shortcode_tags;
     /* ------------------------------------- */
     /* enter names of shortcode to exclude bellow */
     /* ------------------------------------- */
    $exclude = array("wp_caption", "embed");
    echo '&nbsp;<select id="sc_select"><option>Shortcode</option>';
    foreach ($shortcode_tags as $key => $val){
            if(!in_array($key,$exclude)){
            $shortcodes_list .= '<option value="['.$key.'][/'.$key.']">'.$key.'</option>';
            }
        }
     echo $shortcodes_list;
     echo '</select>';
}
add_action('admin_head', 'button_js');
function button_js() {
        echo '<script type="text/javascript">
        jQuery(document).ready(function(){
           jQuery("#sc_select").change(function() {
                          send_to_editor(jQuery("#sc_select :selected").val());
                          return false;
                });
        });
        </script>';
}

There is also a modified code snippet for inserting your own shortcodes, instead of this list.

add_action('media_buttons','add_sc_select',11);
function add_sc_select(){
    echo '&nbsp;<select id="sc_select">
                        <option>Shortcode</option>
                        <option value="[html1][/html1]">[html1]</option>
                        <option value="[css1][/css1]">[css1]</option>
                        <option value="[javascript1][/javascript1]">[javascript1]</option>
        </select>';
}
add_action('admin_head', 'button_js');
function button_js() {
        echo '<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js" type="text/javascript"></script>
        <script type="text/javascript">
        jQuery(document).ready(function(){
           $("#sc_select").change(function() {$("#content").val($("#content").val()+$("#sc_select :selected").val());})
        });
        </script>';
}

I think that's all, I add these fragments as a section “WordPress technical points” as well as in the section “For plugin development“.

Good luck with developing your own plugins.
