OK Thanks. Doing it now

So if I need the student to write: O<sub>2<sub> I can’t?
Also couldn’t find a linear graf. Am I missing that?

OK I wrote this on my functions.php folowing your guid

/* adding buttons to text editor h5p */
function mymods_h5p_semantics_alter(&$semantics, $content_type, $major_version, $minor_version) {
  foreach ($semantics as $field) {
    // Go through list fields
    while ($field->type === 'list') {
      $field = $field->field;
    }
   
    // Go through group fields
    if ($field->type === 'group') {
      mymods_h5p_semantics_alter($field->fields); // Check function name!
      continue;
    }
   
    // Check to see if we have the correct type and widget
    if ($field->type === 'text' && isset($field->widget) && $field->widget === 'html') {
      // Found a wysiwyg/CKEditor field. Add sub/sup buttons.
      if (!isset($field->tags)) {
        $field->tags = array();
      }
	  $field->tags = array_merge($field->tags, array(
        'table',
        'thead',
        'tfoot',
        'tbody',
        'tr',
        'th',
        'td'
      ));
      if (!in_array(‘u’, $field->tags)) {
        $field->tags[] = ‘u’;
      }
      if (!in_array(‘rtl’, $field->tags)) {
        $field->tags[] = ‘rtl’;
      }
      if (!in_array(‘colors’, $field->tags)) {
        $field->tags[] = ‘colors’;
      }
      if (!in_array('sub', $field->tags)) {
        $field->tags[] = 'sub';
      }
      if (!in_array('sup', $field->tags)) {
        $field->tags[] = 'sup';
      }
      if (!in_array(‘img’, $field->tags)) {
        $field->tags[] = ‘img’;
      }
    }
  }
}
add_filter('h5p_alter_library_semantics', 'mymods_h5p_semantics_alter');

But on my tool bar the ‘u’ ‘img’ and ‘rtl’ do not apear

I found out that if I change wp-admin\includes\media.php to:

$attachment = array_merge( array(
		'post_mime_type' => $type,
		'guid' => $url,
		'post_parent' => $post_id,
		'post_title' => $title,
		'post_content' => $excerpt,
		'post_excerpt' => $excerpt,
	), $post_data );

I get the description IPTC to the description field in woordpress.
however I don’t want to change this file I’m looking for a hook that can make it throw functions.php

Hi steve this isn’t duplicate issue.
the post you added was resolved.
this one not yet.
this is a differnt issue

OK found it.
I needed to activate Cache images locally.
If you look in the php file you can see that when it’s not “on” it makes a link to http://quicklatex.com/ and by the way there isn’t https://quicklatex.com/ so don’t change the link
