Exact link of vertical tabs I am using Field Group.

With 2 Vertical Tab, 'Step 1' and 'Step 2'. 

I want to put a link "NEXT" on 'Step 1' that should open 'Step 2', same a back link on 'Step 2' that should go back to 'Step 1'.


I tried different combinations with Multipage but did not work here. How can I do this? I can put text but I don't know how to get the link of the other tabs directly.
Just add the ID of the pane (fieldset) to the URL as a fragment, e.g.

http://example.com/node/[ID]/edit#edit-metatags


Assuming metatag is installed, that code will open the metatags tab directly on page load. 

An example for core might be:

http://example.com/node/[ID]/edit#edit-options


For the "Publishing options" tab.
