After selecting VM set it gets you to a page where you can specify command line
arguments. Type something in and press 'Enter' - it will move to previous page
of selecting VMs which is already done. Expected behaviour will be to move
forward.

--- Comment #1 from François Gouget  ---
This appears to happen because that page has two <input type='submit'> buttons
in the form. Its seems HTML5 specifies that the default button is the first
'submit' button in the form which in this case is the '< Prev' button.

This means this issue also exists on the other pages except it's less visible
when there is no edit field where 'Enter' would be used (On the other pages
'Enter' typically has no effect until you press Tab which puts the focus on the
first link in the page so that pressing 'Enter' then has the obvious action.
But clicking on a checkbox or other form element and pressing 'Enter' would
again trigger the problem).

Also the TestBot CGI framework has no notion of the default 'Action' although
that's usually the last in the list. Which also means it's the last submit
button on the page.

So there are a number of solutions:
* Reverse the order of the buttons. That's not great and not always possible
(see UserList.pl).

* Perform trick to add a hidden version of the default button in the form.

* Use Javascript to intercept Enter and send trigger the expected action.
