We were developing a website that required use by novice users and wanted to eliminate anything that could be confusing. The “Split Summary At Cursor” button on the body field in Drupal served no purpose and could possibly confuse users.

In order to remove it, you must create a module with the following function. Note that our module was named “digitalstax_customizations.”


function digitalstax_customizations_form_alter(&$form, $form_state, $form_id) {
if(isset($form['body_field']['teaser_include'])) {
$form['body_field']['teaser_include']['#access'] = FALSE;
}
}
