On a regular tweet, pressing the right-arrow key leads to an in-app view of the user’s profile, focused on their timeline, with tabs for their replies, their favorites, and their profile data. On a tweet with an image link, it opens the image right within the app. On a reply, it again opens up that conversation view.

In fact, you can navigate Twitter with only the arrow keys, if you’re so inclined. Arrow up and down through tweets, tap right on a conversation to expand it, tap down to go through that conversation, tap right to go into a user’s profile, and so on. Then left arrow your way back out again.

Hold down the Option key when you hit the right arrow, and you get (surprise!) options. On a tweet with an image link, Option-Right Arrow lets you choose whether to see the picture or the user’s profile.

As you arrow through tweets, you’ll note that the scrolling seems to invoke a little bit of gravity. (The same isn’t true for mouse scrolling, though it should be.)

The more you use Twitter for Mac, the more apparent its flaws become, but the more obvious it becomes that this is where the Mac is going. (I could have written, “For better or worse…”, but I’ve become convinced that, long-term, it’s for better, so I dropped the conditional.)
