Focus vs selection events

Hi,

We are using version 6.1.2 for Kanban. We are trying the keyboard navigation. With up/down arrow the next/previous cards are selected.

Example: https://docs.webix.com/samples/63_kanban/01_basic/04_templates.html

We want to separate the focus and selection events. Up/down arrow will change the focus and on Enter/space the focused card should be selected.

Is there any way we can achieve it?
