One of the sections that interested me was about plain text, full-screen word processors. They strip things back to basics to give you a blank screen to focus on, without buttons, popups or a visible Windows taskbar; even formatting options such as italics and bold are gone. Just bang out the words. Removing bloat can increase the power. For a writer these tools make a viable alternative to using Microsoft Word, especially when you are starting from fresh on a new project. Below I have included screenshots and links to the three I plan to spend more time with.
All are free; none need installing, and they seem to be portable via a USB memory stick.
If you use Microsoft Word there are ways of approximating the simplicity. For example, you can press the following keys, one after another, in order to get a full-screen view: Alt V U. Press escape when you want to quit full-screen mode. It is not true full screen though, since it leaves the Windows task bar visible. I also recommend going into print layout first if you have a widescreen monitor (so that you don't wear your eyes out scanning all the way across the width of the screen - full screen print layout keeps the text near the centre). If you have a squarer, 4:3 monitor, then web layout might be fine.
