As soon as it is removed, the little icon for bringing up the keyboard disappears.
I found it. It's that goofy Tablet option for the Taskbar. So, not only does it hide your Taskbar icons but it also makes the Touch Keyboard inaccessible. Great thinking. I can visualize the use-case analysis: Tablet user: Modern UI: TK appears when
needed: Ergo, no need for a keyboard!
But what about the Language settings in the Charms bar? What did they do with them? Can we customize the Action Center buttons? Those need to be put back there. In fact, I can recall earlier in the preview that there were lots more opportunities to
"pin" settings dialogs to the Start screen. How about letting us pin anything from the Settings "app" to the Action Center button array?
Oh. In Typing there is also Automatically show the touch keyboard in windowed apps when there's no keyboard attached to your device. Great. But what if the "windowed app" doesn't have an input area and you want to be able to use some keyboard shortcuts?
More missing use cases.
