### Provide a general summary of the feature here I'd like equivalents of `add` and `remove` methods for selection. ### 😯 Current Behavior Manual implementation like ```ts let nextSelected = new Set(list.selectedKeys); if (list.selectedKeys === "all") { nextSelected = new Set(initialItems.map((metric) => metric.id)); } nextSelected.delete(metric.id); list.setSelectedKeys(nextSelected); ```
