It did. To some extent it seems like it was a telemetry mistake that some of the easier mouse controls (an actual button for start rather than gesture; a missing obvious power button; not having a simple mouse button to get to the Charms; etc). Windows users opted into Windows telemetry all must have seemed to be keyboard-heavy (probably because only certain types of power users, such as myself, were opting in to telemetry). All of the keyboard shortcuts still worked. Some new keyboard shortcuts were added. Windows 8 was extremely useful from a keyboard shortcut viewpoint. (The Charms made a lot more sense from the keyboard.)
