Some of my new testers are hitting the Enter key which saves and closes the test. That test is no longer fully editable and when working with a long test, this is unfortunate. It seems the focus of this page should not be placed on the Save function. Hitting Enter should do nothing. That or allowing the option to re-enter a saved test and continue. Optionally, a Mark Test as Complete function would help. Being able to save a test and return to it should be an option but at the very least, do not save and close the test because someone accidentally hit Enter!
