+Button with a trailing shortcut keycap.
+
+Use this when the action label and shortcut should be taught together at the control level.
+
+### API
+- Inherits Button props.
+- \`shortcut\`: visible keycap text.
+- \`shortcutAria\`: semantic shortcut string for \`aria-keyshortcuts\`.
+- \`shortcutClass\`: optional class override for the keycap.
+
+### Variants and states
+- Uses the same \`variant\` and \`size\` options as \`Button\`.
+- Supports disabled state.
+
+### Accessibility
+- Keep the visible shortcut concise.
+- Use \`shortcutAria\` for the canonical key sequence when it differs from the visible label.
+
+### Theming/tokens
+- Extends \`Button\` and composes \`Keybind\`.
