I have several buttons within a form, depending on which part of form they are on, want the Enter key to trigger different buttons

Hi, 

I have several buttons in my JSF form page. There are also several
input fields. What I would like is when the user is in one particular
text field and hits Enter, I want to trigger the button associated
with it. If I'm in another text field, it should trigger a different
button.

Basically I want to change submit button focus with javascript or JSF
depending on which input field has focus. What is the best way to do
this?
