KeybindingHint

Use KeybindingHint to make keyboard shortcuts discoverable. Can render visual keybinding hints in condensed (abbreviated) form or expanded form, and provides accessible alternative text for screen reader users.

import {KeybindingHint} from '@primer/react/drafts'

Examples

Single keys

Use the full names of the keys as returned by KeyboardEvent.key. Key names are case-insensitive.

render(
  <>
    <KeybindingHint keys="a" /> <br />
    <KeybindingHint keys="B" /> <br />
    <KeybindingHint keys="ArrowLeft" /> <br />
    <KeybindingHint keys="shift" />
  </>,
)

Special key names

Because the + and space characters are used to build chords and sequences as described below, their names must be spelled out to be used as keys.

render(
  <>
    <KeybindingHint keys="Plus" /> <br />
    <KeybindingHint keys="Space" />
  </>,
)

Chords

Chords are multiple keys that are pressed at the same time. Combine keys in a chord with +. Keys are automatically sorted into a standardized order so that modifiers come first.

render(
  <>
    <KeybindingHint keys="Alt+a" /> <br />
    <KeybindingHint keys="a+Alt" /> <br />
    <KeybindingHint keys="Control+Shift+ArrowUp" /> <br />
    <KeybindingHint keys="Meta+Shift+&" />
  </>,
)

Platform-dependent modifier

Typical chords use Command on MacOS and Control on other devices. To automatically render Command or Control based on the user's operating system, use the special key name Mod.

render(<KeybindingHint keys="Mod+Shift+X" />)

Sequences

Sequences are keys or chords that are pressed one after the other. Combine elements in a sequence with a space. For example, a b means "press a, then press b".

render(
  <>
    <KeybindingHint keys="a b" /> <br />
    <KeybindingHint keys="Mod+g ArrowLeft" />
  </>,
)

Full display format

The default condensed format should be used on UI elements like buttons, menuitems, and inputs. In long-form text (prose), the full variant can be used instead to help the text flow better.

render(
  <Text>
    Press <KeybindingHint keys="Mod+Enter" format="ful" /> to submit the form.
  </Text>,
)

onEmphasis variant

When rendering on 'emphasis' colors, use the onEmphasis variant.

const CmdEnterHint = () => <KeybindingHint variant="onEmphasis" keys="Mod+Enter" />

render(
  <Button variant="primary" trailingVisual={CmdEnterHint}>
    Submit
  </Button>,
)
