Angular List - Keyboard Support
An end user can use the following keys to interact with the UI component.
Key | Action |
---|---|
↑ / ↓ | Moves focus to the previous/next item. |
Page Up / Page Down | Moves focus to the item located a screen above/below the current one. |
Home / End | Moves focus to the first/last item. |
Enter or Space | Selects the focused item. |
Shift + ↑ / ↓ | Shifts the focused item one item up/down. Active if the allowItemReordering property is set to true. |
Delete | Removes the focused item. Active if the allowItemDeleting property is set to true. |
Use the registerKeyHandler(key, handler) method to implement a custom handler for a key.
