My TV channel has been changed when someone picks up a key chain with numerous keys on it. We also used to get conversations from next door on our intercom.
I never had cable in my life, never programmed a VCR, DVD player, or even used a T.V. remote.
I did used to play movies on a VCR but that was about the extent of it, I;m not very tech savvy, and Fluther and Worpperfect are about all I ever do with my computer except occasionally looking up information online.
