My mother can no longer use the remote control for her television, because it it too complicated and confusing.
I have found that simplified remote controls are available, with just the On/Off, channel changer and volume adjustment buttons. My mother can use this and is prolonging an aspect of her independence just a littlelonger.
There are several products on the market, but if you are interested I purchased something called the "Doro HandleEasy 321rc Universal Infrared Remote Control", which is stated to work on all UK televisions.
(Sorry, this isn't a question, just thought I'd document it anyway).
