Do not want to tab to next form on a page, stop at submit for each form.

I search all threads, documentation etc. and found how to get tab indexing to work correctly if you want to tab through from one form to the other, but in my case I do not want the tab indexing to jump to the next form, just stop at the submit. So in essence you must click on a field in that form to tab through it, and it stops at the submit. I can't find any jQuery to accomplish this either. It may be a focus control?

I understand tabindex. Are you familiar with a way to stop tabbing from moving to the next form on a page say at the submit button. I don't want tabbing to jump to the next form. I've put 3 forms in coda slider panels, and when it tabs to the next form it totally screws up the sliders panel line up. Trying to do a cool user "select which form" they need on a single page type of thing.
I understand if this is outside of scope. I would definitely share such an accomplishment with others.

None of those will stop tabbing to the next form on the page.
Maybe disabling the tabindex to the submit button to -1 so the tabbing just stops tabbing on the focused form?

For anyone with multiple forms on a page on in a slider like the coda slider, here is a fix if you do NOT want the tabbing to go to the next form. Enter button still work for Submit so it's still accessible.
JS:

$(document).ready(function(evt){

$('.gform_button').live('keydown', function(evt){
    if(evt.keyCode === 9){
        evt.preventDefault();

        var form = $(this).closest('form');
        var input = $('input:first', form);

        if(input !== undefined){
            input.focus();
        }
    }
});
});
