My smart keyboard finally arrived a month after I bought my iPad Pro. There is one key I can't figure out what it does. It is on the bottom left, it looks like a World or Globe icon, it is to the left of the control key. When I press the key nothing happens. My first thought is that it was like the home key, but it doesn't do that. Any ideas?
Just play around with it... when typing it toggles between regular keyboard and emojis... I am sure it has all sorts of functions.
If you have more than one keyboard installed (I have English, Russian and emoji) it will switch between them. A similar globe icon appears on the onscreen keyboard if you have more than one keyboard installed.
The globe icon is in the same position where a "Fn" (function) key resides on a Mac keyboard, so I'm guessing its functionality is similar.

Globe key on Smart Keyboard, what does it do?
