I rely on screenshots for a lot of stuff, until today I didn't know how to get a screenshot in the Windows* 8 tablet-mode UI. Mark at Techrepublic showed me the way here. For me the shortcut is similar enough to the one I use on my Samsung* tablet that I may actually remember.
Windows 8 Screenshot in Tablet Mode = Windows button + Volume down button
Android* 4.x Screenshot = Power button + Volume down button
This PSA brought to you by my need to know these things.
