Question: I was intrigued by this statement by [@DanWilson](http://twitter.com/DanWIlson) on Twitter:

> 
> All Web Developers: Never Ever Ever
>  put anything after the password box
>  and before submit button on a form.
>  Tab MUST go directly to submit.

When I asked for clarification, he added:

> 
> because the UI pattern is Username TAB Password TAB Enter Key.

Can anyone point me to evidence that corroborates or contradicts that claim, even if it's anecdotal?

Answer: 
Egregious breaks in this pattern are when helpful form designers put the Forgot Password link on the tab stop after password and before the submit button. This inevitably results in the page refreshing, a new form loading. Then, when going back, as per good security practices, the password field (which I typed in the first time) is blank.

While I totally respect the aesthetic freedom of designers and developers and I do not want the web to LOOK homogeneous, the behavior of the web should be.

It is irrelevant to respond "I don't use this pattern". Whether or not the pattern is THE dominant one (and your sample-size-one doesn't show this), if it's a significant pattern then it should be respected. Maybe only 10% of users press a tab before enter, but you don't want to piss off 10% of your users for something as simple to fix as this.
