While doodling in MS Word (as you do) I hit the 'Ctrl + Alt + NumPad+' keyboard short cut which changed my cursor to the one shown below (similar to the Mac 'Command' key symbol):

The cursor doesn't seem to behave any differently to the usual cursor and it reverts to normal if you hit the 'Esc' key.
Anyone know what this is all about?
(I'm on Windows 7, 64bit, UK keyboard, Word 2007)
