How to navigate through the li list by pressing down/up keys?

Question

Angular

There is a ul list with elements.

How to highlight list item by pressing up/down keys? Roughly speaking, to select elements?

Tried creating a link to a DOM element:

@ViewChild("SearchList", { static: false }) searchResultList: ElementRef;

Then somehow it is necessary to impose a wiretap on the keydn event
