For me, one of the greatest benefits of computers is their ability to copy and paste content from a wide range of sources (particularly web pages) into one document.
However advantage this is almost entirely negated by the amount of faffing around required to get the text all in the same format.
Luckily, I discovered the wonders of Steve Miller’s PureText. This simple and free application must have saved me tens of thousands of key-strokes over the years, as well as significantly reducing the frustration of trying to achieve something which should have been straightforward in the first place.
