# `Minga.Mode.DescribeKey`
[🔗](https://github.com/jsmestad/minga/blob/main/lib/minga/mode/describe_key.ex#L1)

State for the describe-key meta-mode.

When active, describe-key intercepts all input to walk the keymap
trie and report the binding at the terminal node. The three fields
(`leader_node`, `keys`) always change together: entering describe-key
sets `leader_node` to the trie root, and exiting (via match, escape,
or unbound key) resets both fields by replacing the struct with `nil`.

# `t`

```elixir
@type t() :: %Minga.Mode.DescribeKey{
  keys: [String.t()],
  leader_node: Minga.Keymap.Bindings.node_t() | nil
}
```
