title: HUD
description: The panel that lists a layer's keys while you're in it.
---

When you enter a modal layer, the HUD appears at the top of the main display and
lists what each key in the layer does. It hides two seconds after your last
keypress in the layer, or when you leave it.

<LayerKeyboard compact>
  The Nav layer, entered with <kbd>f</kbd>. The HUD lists the keys it binds.
</LayerKeyboard>

Each entry uses the binding's own label and icon if it has them, so the HUD reads
the way you named things. The **Hints** view on a layer page shows the same grid.

## Showing it yourself

Groups and app layers have no key that enters them, so the HUD doesn't appear on
its own. Bind **Toggle layer HUD** (under Vimputer in the action picker) to show a
layer's keys on demand. A HUD opened this way stays up until you press the key
again.

**Show HUD banner** and **Dismiss HUD banner** put a short message in the HUD,
for example to confirm that a mode changed.
