Selecting Table rows using Arrow keys

Selecting Table rows using Arrow keys

Content

Hi,

Use case - User types in search criteria and tabs out to populate the Search result table. I am able to achieve it.

Expectation - Once the table is populated with Search result, first row should be selected by default which I am able to achieve by keeping selection-required = true. But after that i am not able to select other rows using arrow down key. Its only when I explicitly select a row using mouse , I am able to select other rows using arrow key.

How do I select other rows using arrow down key once the table  first rows gets selected by default. I do not want to explicitly select a row using mouse and then use arrow key. I have a selection listener defined which is working fine.
