Accidently Deleted "Save" Button

[Galwyn]

well i was editting some codes, and i realized that i accidently deleted "save" button at category edit panel(Admin page). i editted many pages, do you know which file includes this code(i have the code but don't know where to put)

In the admin template files, most ***.index.php files have, near the bottom:

  {include file='templates/element.hook_form_content.php'}
  
  <div class="form_control">
	<input type="hidden" name="previous-tab" id="previous-tab" value="">
	<input type="submit" id="cat_save" value="{$LANG.common.save}" class="button">
  </div>
  <input type="hidden" name="token" value="{$SESSION_TOKEN}">

It is the <div class="form_control"> ... </div> block that has the Save button.

The *** is 'category', 'customers', 'products', etc.
