My thanks to Peter Povinec for the solution, which he found here:

These are hotkeys that come from a recent Intel graphic chip. The
C-M-<arrow> keys actually rotate the display!

Here's how to turn off all such graphic hot keys, for others who might be

Right-click the desktop > Settings tab > Advanced > Click the bar across the
top, behind the tabs (the bar is labeled "Intel(R) Graphics Media
Accelerator Driver for Mobile") > Graphics Properties... > Hot Keys >
uncheck Enable Hot Keys > OK > OK > OK.

Whew! Thanks, Peter. Crazy, huh? - Drew
