Yes it does. As long as you set both the name and value:

<INPUT name="submit" value="submit" type="submit"/>

In fact you can have multiple submit buttons on the same page and you can detect which one is clicked on by checking for this pair.

Using uppercase tags but xhtml-style tag closing = fail ;) – ThiefMaster Jan 25 '11 at 19:39

JS on MSIE has also some itchy issues when using `name="submit"` on a form element ;) – BalusC Jan 25 '11 at 19:43

Yes, submit buttons are submitted with their name/value.

But especially when doing i18n, it's recommended to rely only on the name, not the value though so you don't have to check for i18n'd values in your server-side code but just for the existence of certain POST arguments..

If it is part of the submitted form, yes.
When a form is submitted, every one of it's "input" elements are posted; and if you submit a form by clicking it's submit button (which is another input) you'll definitely post it too.
If you don't want to do that, you can always submit you form via javascript : form.submit();.
You can add a button element to your form and attach a function that submits the form to it's click event.

<button type="button" onclick="document.getElementsByTagName('form')[0].submit();">
    Submit the form!
</button>

That way you'll have a submit button inside your form that is not submitted:)
