Last week I was travelling the country talking to academics and students about the opportunity of building apps for Windows 8.
During the week I had a number of really interesting discussions, however on Friday I had a comment from one student, who simply believed Windows 8, was for touch devices only.
We got onto the topic of keyboard and mouse as I was presenting using a Lenovo thinkpad which supports both touch and keyboard and mouse. I was simply demonstrating Windows navigation via touch and then via keyboard and mouse during the presentation demos and the student in question seemed to be blown away by this and when we discussed this it more detail after the event he wasn't aware of the number of Windows Shortcut keys available.
So here a quick list of some of my favourites
Charms and menus
Apps Search Screen
Files Search Screen
Split to the right
Split to the left
Scroll Start Screen
Apps Options/App bar

Perhaps you should have listened to this "one" student?
