Answer 1

There are a js-free solution.

Set type=submit to the button you'd like to be default and type=button to other buttons. Now in the form below you can hit Enter in any input fields, and the Render button will work (despite the fact it is the second button in the form).

Example:

    
        Edit program
    
    
        Render
    

Tested in FF24 and Chrome 35 (formaction is html5 feature, but type is not).
