HTML DOM accessKey (MAC)

The accesskey property is standard html, HTML DOM accessKey Property that uses a keyboard combination on a webpage to focus the cursor in a specified field. On a PC, [Alt] + accesskey works and I can be program my DS2208 with Send Alt Key <ALT ]>.

] is the accesskey for the web page.

On the Mac, [Control] [Alt] + accesskey is needed for the accesskey function to work a Mac web browser. I have had no luck figuring out how to program the scanner to work on a Mac

Does anyone know how to program a scanner to send multiple key combinations to work with a Mac?

Is there an ascii value for the mac keyboard control key?

Any ideas would be appreciated.
