Re: Identifying if focus is visible

Thanks, my IT department just re-imaged my machine without me having a chance to grab NVDA plugins. My reading of the documentation on this plugin, was I thought it would generate a sound if Focus was on an off-screen item. I suppose it could also check that the CSS properties are appropriate. In any case, I plan to download tomorrow.


Best wishes,

Jonathan Cohn
