| `Right` | Focuses the next tag item in the selected list. |
| `Delete` or `Backspace` | When the focused item is a tag list, removes the item from the selection. |

**KB navigation applied to the PopupList**

| Shortcut | Behavior |
|----------|----------|
| `Shift Up` | Adds previous item to selection. |
| `Shift Down` | Adds next item to selection. |
| `Ctrl Shift Home` | Selects all items up to the beginning of the list. |
| `Ctrl Shift End` | Selects items down to the end of the list. |
| `Ctrl A` | Selects all items present in the list. |
