Wordpress Move Button In Posting Page And Add Return Function

i use this to add a button in my posting page

// add more buttons to the html editor
function wptit_add_quicktags() {
?>
    <script type="text/javascript">
    QTags.addButton( 'wptit_pre', 'Gallery', '<a href="http://url.com" target="_blank">See The Full Gallery Here</a>', '', 'g', 'See The Full Gallery tag', 1 );
    </script>
<?php
}
add_action( 'admin_print_footer_scripts', 'wptit_add_quicktags' );

Code (markup):

someone helped me on another forum but didnt do everything i wanted


i want the button the last button, all the way on the rite, its the first button now



i want the button when hit to add the return key, as if the return has been hit and then this html

if i have the cursor after the text and hit the button this is what the button does



return and it goes to a new line and the html is added

 

use advanced visual editor ( there are many plugins)
