Yes/No change to On/Off

I saw recently a discussion regarding changing the Yes/No on a Boolean control to something else like... On/Off or Black/White.

For the life of me, I cannot find it now.

Any link of advice would be appreciated.

Do you mean this

That'd be it....

Thanx a heap.

Hmmmm.... that worked....

Wondering now how to increase the width of the switch.

but what a pain in the ass (aka time sink) to fiddle with it, geez thats a shitty solution
