Settings > General > Keyboard > Shortcuts Toggle?

I'm running iOS 10.0.2 on both my iPhone 7 Plus and my iPad Pro 12.9.

When I go to Settings > General > Keyboard on iPad Pro, there's a toggle switch for "Shortcuts" below the toggle for "Enable Caps Lock" and above the toggle for "Predictive." (Note that the "Shortcuts" toggle also appears on an iPad Air 2 running iOS 10.0.2.)

On iPhone 7 Plus, however, there is no such "Shortcuts" toggle.

Since, on that same Settings page, both devices have a "Text Replacement" option which you can tap on to enter custom keyboard shortcuts, I have no idea what the "Shortcuts" toggle on iPad is for.

I've done about a million different Google searches and haven't found the answer.

Could someone kindly enlighten me?

Thank you.
