[Huzaif-nabi]

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

The main navigation dropdowns cannot be opened using the Enter key when a screen reader is active, preventing keyboard-only users from accessing sub-menu links.

Reproducible demo

No response

Steps to reproduce

1. On Windows, turn on the Narrator screen reader or any other screen reader.

2. Open the Docusaurus website in a browser.

3. Use the Tab key to navigate to a dropdown menu in the navbar, like the "Canary" version switcher or the "English"
   language switcher.

4. Press the Enter key.

Expected behavior

The dropdown menu should open, allowing the user to navigate the options.

Actual behavior

Nothing happens. The dropdown menu does not open when Enter is pressed.

Your environment

• Public site URL:
• Docusaurus version used:
• Environment name and version (e.g. Chrome 89, Node.js 16.4):

Self-service

• I'd be willing to fix this bug myself.

Did you try to use space bar instead of Enter key ?
