Auto-generated from the config schema in the source — see the [config guide](https://jbrowse.org/jb2/docs/config_guide) for concepts. Built into JBrowse core. [View source](https://github.com/GMOD/jbrowse-components/blob/main/packages/display-kit/src/hiddenLegendConfigSchema.ts).

The `legend` of a display whose key is off until asked for, a matrix's
color ramp or the reads' fill.

## Config slots

A setting written to it names members one by one: a member left out stays as it is, and `null` resets one. Slot types (`fileLocation`, `frozen`, ...) are explained in the [config slot types reference](https://jbrowse.org/jb2/docs/config_guides/slot_types). Slots a base configuration contributes are listed here too, so this table is the whole surface.

| Slot | Description |
| --- | --- |
| **show**<br>[`boolean`](https://jbrowse.org/jb2/docs/config_guides/slot_types#boolean) = <code>false</code> | draw the key |
