I praised ⌘⇥ recently in my essay for cleverly not showing itself when you press the keys really fast.

Here’s another nice detail. If you press and hold ⌘⇥, you will eventually stop at the end. (You can then press ⌘⇧⇥ or ⌘` to go in the other direction.)

However, if you are already at the end, pressing ⌘⇥ again wraps around to the beginning:

The issue of whether to wrap around or not is more universal; you can see it in many lists, ⌘F, and so on. On one hand, it’s nice to have a solid deterministic stopping end that you can rely on, especially since sometimes the last item on the list is special (“See more items…”). On the other hand, going all the way back from the end can be frustrating, too, especially on a Mac that does really strange things with Home/End/PgUp/​PgDn keys.

I thought the hybrid approach that ⌘⇥ is doing here was clever, and might be applicable elsewhere.
