[orca-list] Custom keybinding for firefox

[Edhoari Setiyoso <edhoari s gmail com>]

Hi list,

I'm using google translate to study by typing the word/sentence and then press a button to hear the result. 
After typing words, I need to tab multiple times to reach play button and back again to edit field.
I would like to create script which will create new keybinding in firefox or chrome that can find the button 
that I want, click it, and return back to edit field.

Does orca has this feature and where should I look?

Best Regards
