You can

• Allow index
• remove index part from template
• I think you can use surveyurl?move=stepNumber : can you try ?

Else you need a form with a onlick event ....

See : https://www.limesurvey.org/forum/can-i-do-this-with-limesurvey/104218-em-link-to-question-group#134511

More easy in 3.0 :

<a href="#" data-limesurvey-submit="{ 'move':1 }">Go to step 1</a>

Does the trick for javascript

For 'No JS' <button type="submit" name="move" value="1"> Go to step 1 </button>

Must control without index activated. But if needed : just remove {QUESTION_INDEX_MENU} and {QUESTION_INDEX} from template

PS : you can , too :
Remove {QUESTION_INDEX_MENU} + {QUESTION_INDEX} from template and add it only in last question.
