OSX shortcuts - CMD instead of CTRL
OSX uses the CMD key instead of the CTRL key to trigger a shortcut.
I tried to change e.ctrlKey to e.metaKey in app.js, but that was not working.
I think you should change the "ctrl+..." commands code to the new
chrome.commands.onCommand API.

The commands API is meant for shortcuts anywhere in the browser. Also in the Smart RSS tab the shortcuts depended on what column has the focus right now.... Changing the line "if (e.ctrlKey) str += 'ctrl+';" to "if (e.metaKey) str += 'ctrl+';" sounds like good idea, but if that doesn't work then perhaps some other change is required. It is hard to debug for me a I don't own mac or any apple device. Perhaps I can run OSX as VM.
Ok, let me do some other testing and I will let you know if I manage do get the shortcuts work ;-)
