The Submit action specifies a target form in which to submit. While recording, this action is only generated if the form has no Submit button and the user presses the [Enter] key within the form.
This action is made up of a single target locator and requires no other properties.
It is recommended to use this action when a Click action or pressing the Enter key within the appropriate areas of the form are not options.
