Grid cell focus Space keyboard shortcut

vaadin-grid supports focusing on cell components, as shown in How can I forward typing a Space to switch a toggle (custom element) inside that cell? If the toggle is used outside of grid, it can be focues by Tab and toggled by Space.

I have noticed in multi-select mode that I can type Enter step into the cell and there I can use Space to toggle the vaadin-checkbox inside the selection column

@determined-zonkey , any ideas?
