SCREEN DEFINITION (Line By Line):
In viewing a post (aka, “article”), this is how the screen is organized.
At the very top you will see the web site title,  followed by the words 
“Aaarrrggg!”
Next down are two nav buttons labeled  “HOME” & “ARTICLES”.  
The  HOME button  allows you to read all articles in chronological 
sequence. The ARTICLES button shows the titles of  posts that can 
be read by clicking on the title. 
Next down is the title of the current post you are viewing, 
followed by  the date and time the post was created.
Next down is the body of the post which is the author’s content. 
After the author’s content, at the very end, the AUTHOR  is identified.
The next line down presents  TWO CATEGORIES BUTTONS in which the 
post  participates. The two categories buttons appear to work  by bringing 
up the ARTICLES list of titles of those posts appearing in the category 
corresponding to the button selected. Any specific post  is  not allowed to 
participate in any more than two categories. This makes it necessary to 
provide a list of all categories in the LINKS WINDOW which is  
described herein shortly.
The TWO CATEGORIES BUTTONS are followed by
the  NEXT & PREVIOUS BUTTONS which appear to work as expected. 
You can ignore the line containing RSS / Atom
Finally, at the very bottom is the LINKS WINDOW which allows for navigation to
specific posts or other non-post areas.  
NAVIGATING THIS TEXTPATTERN BLOG:
You can see all articles in reverse chronological sequence  by clicking on the HOME  button at the top of this page.  Clicking on the ARTICLES button will list the titles of the oldest posts not including this welcome post.  
To read post in chronological sequence, you can click on the “next” button further down this post. If you have hit the last post, the “next” button will not show. But a “previous” button will show until there are no more prior posts. Note at the bottom of this post, there is no “previous” button, because this is the very first. hence oldest post of all.
At the very bottom are links to:
1. Come back to this WELCOME page.
2. LEAVE BLOG  back to the website.
3. Enable the administrator to LOG ON.
4. A list of links to the first & oldest article of a category.
 To view all articles in a  specific category,   click on the  specific category  link  to get to the the very first posted article in this category.  To get further articles in the category, DO NOT click on the same category link you did the first time. Instead click on the CATEGORY BUTTONS  at the bottom of the post. This will bring up a list of the titles of more posts in the category where you can click on the title of any particular post of interest to you.
