Firstly, this is 'my' list of instructions that I've compiled for personal use so I don't have to keep searching for them on the web. This is one of the reasons I set up this website so it can be accessed from a USB drive.
Secondly, I've repeatedly found helpful instructions during my various learning phases. If I can be of assistance to someone else, that's great.
What I describe here is how I used it. A few pieces of content are simply taken from a help file.
Some knowledge 'evaporates' over time if I don't apply it regularly. Sometimes links on the internet change, or the content has been removed. Where applicable, I have listed the sources at the end of each article.
Note: Some pages contain fixed, pre-formatted areas. In these areas, the display cannot be adjusted to small screens. A scroll bar then appears at the bottom of the screen. The non-proportional display, especially on mobile devices, is not always appropriate. The character sets are not available on all devices.
