Feature Request: Add Cmd+K / Ctrl+K Shortcut to Open Search

[KhanjarSingh]

Is your feature request related to a problem? Please describe.
Currently, the MathJax documentation already includes a search button in the top navigation.
However, there’s no keyboard shortcut to open the search box quickly.
Most modern documentation sites allow pressing Cmd + K (macOS) or Ctrl + K (Windows/Linux) to instantly open the search dialog — this greatly improves accessibility and speed.
It’s slightly inconvenient to manually click the search icon each time.

Describe the solution you'd like
Add a global keyboard shortcut:

• Cmd + K (macOS)
• Ctrl + K (Windows/Linux)

This shortcut should trigger the existing search modal or input box without requiring a mouse click.

Describe alternatives you've considered

• Manually clicking the search icon (works, but slower).
• Using browser search (Ctrl + F), which only searches the current page.

Additional context
Implementing this would align MathJax Docs with the UX standards of modern documentation frameworks such as Docusaurus, VitePress, and Next.js Docs, which all support Cmd + K to open search.

@dpvc I think this is a great feature for someone like me who frequently uses this shortcut.
I’d like to work on this issue and implement the feature on the MathJax documentation site.

Sorry to not get back to you on this earlier.

Note that the documentation already has a hot-key for opening the search dialog. It is the / key, which is the standard key used on read-the-docs, which is the site that hosts our documentation. Can you get by with that?

f you want to research whether there is a way to configure the read-the-docs hot-key code to add a key binding, I would be willing to add the ones you are asking for, but I'm not looking to add custom javascript to the site for this.

@dpvc Thanks for the update! Yes, the / shortcut works for me.
I’ll check whether Read the Docs allows adding extra key bindings without custom JavaScript.
If it’s possible through configuration, I’d be happy to add the Cmd+K / Ctrl+K shortcuts.
I’ll update the issue once I find out.
