How to change node save button text? I found a discussion with some methods for d6 here http://drupal.org/node/344802
on how to change the node "Save" button text to sg else.

Any tips for d7? I would prefer to use form api.
you could use string overrides module or use hook:

function yourmodule_form_alter(&amp;$form, &amp;$form_state, $form_id) {
  if ($form_id == 'name_of_form') {
    $form['actions']['submit']['#value'] = 'Your button text';
  }
}
