Hit Control-Shift, and urxvt (rxvt-unicode) goes into Unicode digit
acquisition mode. Release Control, and it goes into "keycap insertion
mode." Jason, perhaps some keys you press in one of those modes cause ^P
or something similar to be generated.

I use rxvt-xpm nowadays because of such strangeness.

That's probably what happened.  Thanks for the help everyone.  I'll
try not using urxvt for a while.
