### ListKeyManager `ListKeyManager` manages the focus in a list of items based on keyboard interaction. Intended to be used with components that correspond to a `role="menu"` or `role="listbox"` pattern. #### Properties ##### `activeItemIndex` Index of the currently active item ##### `activeItem` The active item #### `tabOut` Observable that emits any time the <kbd>Tab</kbd> key is pressed, so components can react when focus is shifted off of the list. #### Methods ##### `withWrap(): this` Turns on wrapping mode, which ensures that the active item will wrap to the other end of list when there are no more items in the given direction. ##### `setActiveItem(index: number): void` Sets the active item to the item at the index specified. ##### `onKeydown(event: KeyboardEvent): void` Sets the active item depending on the key event passed in. ##### `setFirstItemActive(): void` Sets the active item to the first enabled item in the list. ##### `setLastItemActive(): void` Sets the active item to the last enabled item in the list. ##### `setNextItemActive(): void` Sets the active item to the next enabled item in the list. ##### `setPreviousItemActive(): void` Sets the active item to a previous enabled item in the list.
