add to cart button names

is it possible to write different names for the "add to chart button"
something like that

Through your administration panel, go to Hikashop > Configuration > Languages > Edit, and add the key ADD_TO_CART="Buy online" (or whatever you want into the quote) into the Override field.

i need 2,3 etc. different buttons

i tried that

<a class="hikashop_html_add_to_cart_link" href="http://localhost:8888/demo/index.php?option=com_hikashop&ctrl=product&task=updatecart&quantity=1&checkout=1&product_id=4">buy online</a>

<a class="hikashop_html_add_to_cart_link" href="http://localhost:8888/demo/index.php?option=com_hikashop&ctrl=product&task=updatecart&quantity=1&checkout=1&product_id=4">add to cart</a>

I'm not sure to understand. Why would you want different buttons for ? Do you want the buttons doing the exact same thing ? If yes, when would you want to display one instead of the other ? Or maybe you want to display them both at the same time but that would mean two different buttons for only one action..
