on Enter key press for submitting the filter criterion

Content

Hi, we have few filter parameters which are used with Input Text/Input Number or Select One tabs. Requirement is to submit the form on Enter key press. Entire form gets submitted after enter key press on Search button or on each filter criterion. 

we followed below blog and implemented event action chains on Search for keyup event where $event.keyup == 13 for each filter criterion.

But, along with Enter key even the TAB key press is submitting the form which is not expected. 

Tried to exclude tab key by changing the criterion to $event.keyup == 13 && $event.keyup != 9 or using keydown or keypress events.
