# insert at index

This block is part of the [`redis`](https://docs.rual.nl/block-types/redis) group and was last modified in core [`v13.0.7`](https://docs.rual.nl/core-versions/130007).

### Redis Key Selection Required

This block relies on a Redis key to perform its redis releated actions. You must manually select the Redis key you want to use in the flow in the blueprint using the Redis key selector modal. To access the modal, click the white button on the block.

A typical wiring for [insert at index](https://docs.rual.nl/block-types/redis/redis_list_insert): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `list` pin; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `target` pin; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `element` pin; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%20ui/state_debug).
