Sorry for newbie question. After a while, Emacs starts behaving all
the time as if I have typed C-SPC. That is, whenever I move point, the
text between point and the previous location of point is highlighted.
Turning off CAPS LOCK does indeed seem to be the answer. I wonder why
that should be the case, though?
Because Caps Lock is very similar to holding down Shift, and holding
down Shift while moving point is a CUA gesture for extending the
region.
