This plugin allows you to specify the form element on which the initial focus
should be set

• Only sets the focus if the user is yet to type anything into the form field
• Also supports setting the focus on select elements, radio buttons and checkboxes as well as buttons

Using it is as simple as calling:

$('form > input:first').formFocus();

Please note: jQuery selectors that return more than one element are not
supported as only one element can receive the keyboard focus at a time.
