David Chartier:

When using a hardware keyboard with iOS 9, you can hold the Command key to view a cheat sheet of an app’s shortcuts (assuming its developer has updated to add some). But I noticed this morning that those shortcuts can be contextual, based on the task at hand or which panel or tab you are currently viewing.

Interesting. Check out the images in the post for more on this, especially if you’ve never seen the iOS 9 keyboard shortcuts menu before.
