no, that's something i'm actually starting to get sick of with most native mac apps: it's mandatory to use modifier keys.

:(

single key has been my new favorite "minimalist" feature to use on the mac.

⌘-} in Chrome and Firefox. ⌘-] navigates history in those 2 browsers, which works more consistently than backspace too.

I actually find that to be more awkward than ctrl+tab, which is Firefox's default. I just find J and K to be less of stretch for my pinky.
