- <li><b>Getting and sending files.</b> You can upload or download files to/from your UNIX
- service provider using the commands in the Communications menu.
- <li><b>Copy, Paste, Capture screen or incoming text</b>
- <li>And, of course, <b>access to your UNIX programs</b> like mailreaders, newsreaders and all
- the other things you normally do online.
- <li><b>Did someone send you a mail message with an interesting URL to check out?</b> While you
- are reading the message, you can highlight and capture that URL (using the Communications/Get Highlighted URL
- menu item), and the next time you switch to SlipKnot Web, it will retrieve it for you.

- <ol>
-
- <li><b>Background document retrieval</b> allows you to look at other documents while SlipKnot
- communicates.
-
- <li><b>Save your documents in folders.</b> SlipKnot is the only WWW browser (at this time) that
- allows you to save entire documents (including embedded graphics) for later viewing. Create your
- own named folders (press the Documents/Folders menu item or the Folder icon), and save any document
- by selecting the File/Save menu item in the document's window.
-
- <li><b>Bookmarks</b> allow you to save just the addresses of documents you have retrieved, and then
- retrieve them again when desired.
-
- <li><b>Comments:</b> whenever you save a document or a bookmark to a document, SlipKnot will prompt
- you to save a comment along with it, so that you can selected the document by browsing through
- your own commentary.
-
- <li><b>Print your documents</b> from the File/Print menu item in the document window.
-
- <li><b>The "Retrieve embedded graphics?" option</b> (under the Configure/Preferences menu), tells SlipKnot
- whether or not to get the pictures inside your documents. Turning this option off often significantly
- speeds up retrieval because the embedded pictures are not retrieved. Hint: if you are
- doing quick browsing, turn this option off. Then if there is a document whose pictures you want to
- get, turn the option on, and then press the "Retrieve again!" menu item in the document window.
-
- <li><b>Queueing up retrieval jobs.</b> You don't have to wait for a document to come in before
- requesting another. Your requests are queued, and when one has been satisfied, the next
- requested is automatically started. You can even <b>queue up retrievals while you are offline,</b>
- (by simply clicking on the documents you want to retrieve),
- and when you log in next time and enter SlipKnot Web, it will retrieve those documents and files
- for you. If you have jobs queued up, you can <b>pause</b> the queue, and change the order of jobs, etc.
-
- <li><b>Minimizing windows.</b> 10 screen documents can clutter up your screen quickly. Press the
- minimize button on the upper-right of a document window and the document will disappear and
- be replaced by a numbered button at the top of the screen. Press the button, and the document
- will reappear (try this now).
-
- <li><b>One document hidden behind another?</b> Use the Windows menu item
- to select documents that may be partially hidden.
-
- <li><b>Display up to 10 documents at once.</b> Not enough? SlipKnot keeps an unlimited history
- (limited only by disk space) of all of the documents displayed in the current session. Press
- the menu item: Documents/History to redisplay any document (or press the circular arrow icon). All
- such unsaved documents will be erased when next you start SlipKnot.
-
- <li><b>Use SlipKnot to display your saved documents without logging in -- for instance, for offline Demos.</b>
- You do not have to log in to your UNIX host to start SlipKnot WEB! Just press the "World Wide Web" button
- in SlipKnot Terminal. There, you can display previously retrieved documents, or ones that you have created.
- And it will follow links embedded in these documents (even search your folders for the appropriate document
- to satisfy a link).
-
- <li><b>Use SlipKnot to develop your own documents.</b> You will need to learn HTML (Hypertext
- Markup Language). After you've gotten the hang of HTML, create an HTML document in a file with the
- .HTM suffix. In SlipKnot, press the "Navigate/Display Local HTML File" menu item to display the
- current state of your document. If there are problems, don't close the document -- simply go
- back to your text editor, make changes, save the file, go back to SlipKnot and press the
- "Retrieve Again!" menu item and SlipKnot will show the newly updated document. That is how we created and
- edited this SlipKnot Features document.
-
- <li><b>Use SlipKnot to retrieve anonymous FTP files and directories.</b> No need to run anonymous FTP from UNIX:
- simply press "Navigate/Get document from the Internet" and type in the URL (Universal Resource
- Locator) for any Internet file or directory you want to retrieve. The file does not have to be a displayable
- document -- it can be any file anywhere that you are allowed to retrieve via anonymous FTP. Here's
- how you use this feature. Suppose you want to get a file called a.zip in a directory called
- /public/programs at a location called ftp.majorsite.org. After pressing the menu item mentioned above,
- type in the location as: <code><b>ftp://ftp.majorsite.org/public/programs/a.zip</b></code> and SlipKnot will
- then download the file to your SlipKnot download directory. Or, just type in
- <code><b>ftp://ftp.majorsite.org/public/programs/</b></code> and you will see the directory, from which you can choose
- files to download.
-
- <li><b>Use SlipKnot as a Gopher.</b> No need to run the gopher program in UNIX: if you know the URL of the gopher
- site you're interested in, just use SlipKnot Web's "Navigate/Get" menu item. For instance,
- one such URL is: <code><b>gopher://gopher.tc.umn.edu/</b></code>

- <h1><a name="How">How SlipKnot works (what's behind the curtain)</a></h1>
- First of all, SlipKnot is actually two, independent cooperating programs: SlipKnot Terminal
- and SlipKnot WEB.<p>
- The Terminal is what you see when you first execute SlipKnot. It provides you with an ordinary
- terminal session into your service provider's UNIX system.<p>
- The WEB renderer (SlipKnot WEB) is a different program that is launched by the Terminal when
- you want to browse the World Wide Web. It paints and prints the documents, manages folders, keeps the
- retrieval job queues, etc. (You are now using the WEB renderer.) <p><p>
- Here's what happens when you request a document to be retrieved, either by pressing on an
- underlined link or typing in the name explicitly:
- <ol>
- <li>The WEB renderer sends your request to the Terminal (which is still active but invisible).
- <li>The Terminal sends the request to your service provider's UNIX system. In effect, it executes a standard
- UNIX command to retrieve the document or file from the remote internet computer.
- <li>The Terminal checks the status of this UNIX request periodically, and if it fails for
- any reason, it tries again.
- <li>When the file has been retrieved from the remote machine, it is placed by your UNIX system
- inside your personal directory on your UNIX system.
- <li> The Terminal then starts downloading that file to your PC.
- <li> When Terminal is finished, it sends a message to the WEB renderer indicating that the requested
- file is now available on your PC.
- <li>The WEB renderer scans the file, looking for references to any pictures that must be included
- in the document when it is displayed (the pictures are inside separate files on the remote computer).
- <li>If the WEB finds that there are pictures to be retrieved, it sends these requests to the Terminal,
- which retrieves them one by one.
- <li>When all of the necessary files have come in, the WEB renderer converts the images, and then
- "plots" the document (does the layout according to the typefaces you've specified in your Configure
- options). Then the document appears.
- </ol>
- <p>
- The separation of these two functions (communications by the Terminal, display by the WEB renderer)
- allows retrieval to be done in the background, while you are scrolling and reading documents in
- the foreground.<p>
- <b>Design note: SlipKnot was specifically designed for modem users. Unlike other World
- Wide Web browsers, SlipKnot understands that its users will have to wait a while for each
- document to be retrieved from the internet. Therefore, we included many features to allow
- multiple documents to be seen, stored, and printed to prevent you from having to retrieve documents
- unnecessarily.</b>

-
- <h1><a name="Forms">"Fill-in" Forms</a></h1>
- SlipKnot handles documents with "fill-in" forms in two different ways:
- <ol>
- <li><b>Normal</b>: you can fill out the form on the screen and send the
- information back to the server. (you need not read the explanation
- below).
- <li><b>Abnormal/old</b>: if you do not have lynx version 2-4-2 or 2.4-FM on
- your UNIX system (or cannot access it), and the fill-in form is of the
- "POST"-type, then see below on how to use lynx directly to answer the
- form's questions.
- </ol>
- <p>
- <b>Filling out forms using lynx</b>: SlipKnot helps you by allowing you to go back
- to SlipKnot Terminal, and then automatically retrieving the document using the
- "lynx" program.
- <p>
- Lynx will display the page and allow you to fill in the responses to the questions in
- the document. You will need to know how to control lynx using your up and down-arrow
- keys and various single letter commands. Help for doing this can be found
- in SlipKnot online Help, under the topic: <b>Forms</b>.
-
- Whenever a document is retrieved by SlipKnot Web that contains forms, there
- will be a white picture inside the document where the form questions would
- normally appear. Also, there will be a new "forms" menu item in
- the document window. Use this menu item to activate the return to Terminal,
- and the automatic retrieval of this document by lynx.
- <p>
- Once inside lynx, you can browse the Web at high speed.
- <p>
- <h4>Retrieving a URL whose address you can see in SlipKnot Terminal</h4>
- While using lynx, or reading mail, if you come across a document address (URL)
- that you would like SlipKnot Web to display graphically, you can use
- the following simple technique to capture the URL.
- <p>
- <b>From inside lynx:</b>
- <ol>
- <li>press the "=" key to tell lynx that you want to
- know the address of this document
- <li>highlight the URL of the document
- <li>press Ctrl-F8 or the menu item Communications/Get Highlighted URL
- <li>press "q" and then "y" to exit from lynx
- <li>press the World Wide Web button to return to SlipKnot Web, which will
- automatically retrieve the document for you.
- </ol>
- <ul>
- <li><b>Note: </b>If you get stuck trying to retrieve something in lynx,
- use your UNIX interrupt key (probably Ctrl-C or Del) to terminate lynx.
- </ul>
- <p>
- <b>From inside your mail program, or a newsreader:</b>
- <ol>
- <li>highlight the URL
- <li>press Ctrl-F8 or the menu item Communications/Get Highlighted URL
- <li>get to your shell prompt (either exit the mail or newsreader program, or,
- if you know how, "shell out" to your UNIX prompt).
- <li>press the World Wide Web button to return to SlipKnot Web, which will
- automatically retrieve the document for you.
- </ol>
- <p>
- <b>Note on "Authentication"</b>
- Some Web sites require you to enter access codes (passwords) to retrieve their
- documents (for instance: HotWired). You must stay inside lynx while retrieving
- their documents; SlipKnot will not be able to get through to these sites.
-
- <h4><b>As practice for Forms:</b></h4>
- Here is a very useful site for searching the Web for documents of interest:
- <a href="http://akebono.stanford.edu/yahoo/bin/menu">The Yahoo Main Page</a>.
- Inside this document, you will find a link for searching. If you retrieve
- this "search" link, the document will have a form to fill in the keywords
- you'd like to search on, and you can then exercise the SlipKnot Web Forms
- menu option.

-
- <h1><a name="Gopher">Gopher</a></h1>
- "Gopher" is a browsing mechanism that predates the World Wide Web. Nevertheless,
- there are a vast number of documents that are accessible though it. Gopher
- URLs start with "gopher://" instead of the Web's "http://". On the SlipKnot
- Local Home Page, there is a Gopher link to the University of Minnesota, where
- Gopher was born (I believe it's named after their mascot). You can use Gopher
- to browser through both documents and files worldwide, and then retrieve the
- documents or files from the displayed listings.
- <p>
- <b>Note: Gopher support is only available to registered SlipKnot users.</b> Once
- registered, this feature will be unlocked inside SlipKnot.

-
- <h1><a name="FTP">FTP</a></h1>
- SlipKnot can retrieve both files and directory listings available via
- anonymous FTP. The URL for FTP retrievals starts with: "ftp://". As practice
- for FTP usage, you can take a look at our anonymous FTP directory (one of the
- our two sites that carries SlipKnot upgrade files). There may not be
- anything terribly interesting there, but you will be able to see
- <a href="ftp://interport.net/pub/pbrooks/slipknot/">what directory listings
- look like.</a>

-
- <h1><a name="Telnet">Telnet</a></h1>
- As you probably already know, Telnet is the name of a program that allows you
- to log into and interact with a computer somewhere else in the world. In some
- Web documents that you may receive, there will be Telnet links, along with
- instructions on how to log into the computers named in the link, after you actually
- make the connection.
- <p>
- When you click on a Telnet link, SlipKnot Web will take
- you back to SlipKnot Terminal, and execute the Telnet program with the
- appropriate address. SlipKnot Terminal is already a terminal
- program, and this just what is needed to log into the remote computer
- named in the link. After finishing with the remote computer session,
- you can terminate your Telnet session, (log off, and then type "quit" or
- "exit" to the Telnet prompt), get back to your UNIX shell prompt, and
- press the World Wide Web button to return to SlipKnot Web.

-
- <h3><b>The Job Queue</b></h3>
- You probably already know that you do not have to wait for a document to
- arrive and be displayed before clicking on another link (in a document that
- you are looking at). If you do this, a little message will come up (and
- will automatically disappear after a couple of seconds), that the retrieval
- request you just made will be put onto the Job Queue.
- <p>
- To see what has been queued up, press the "See Jobs!" menu item at the
- top of the screen. You can queue up to 50 requests for retrieval -- this
- makes it possible for you to request all of the documents that you see links
- for in a page, one after the other, while any one of them is downloading.
- You can also change the order of the requests and cancel them by using
- the "See Jobs!" menu item. There is also a "Pause" option, so that you
- can go back to SlipKnot Terminal temporarily to do some UNIX work (mail, or
- news reading), and then resume the retrievals when you get back to SlipKnot
- Web. Finally, you can Pause this job queue, and actually terminate
- SlipKnot -- the requests will be resumed when you activate SlipKnot Web the
- next time.
- <p>
- This feature is another browser innovation designed specifically for
- modem (low-speed) Web users. Given that documents take some time to arrive,
- you should at least be able to order ahead.
- <p>
- <b>Notes on the job queue:</b>
- <ul>
- <li>If you ask for a
- file that require a viewer to process, when SlipKnot retrieves that file,
- it will pause the job queue until you view the file or save it.
- <li>Assuming that you have set the number of visible windows to 5 (in Configure/Preferences),
- after 5 documents have been displayed on the screen, SlipKnot will
- retrieve the 6th document, and retire one of the documents on the screen
- to the History folder to make room for another window.
- <li>Given the time it takes for large documents to come in (or large files
- via FTP), if you have many queued up, perhaps you might consider going
- out to lunch, or dinner, or getting married, and then coming back for the
- results.
- </ul>

- <hr>
-
- <h3><b>Personal Home Pages</b></h3>
- Under the Configure/Preferences menu item, you can tell SlipKnot to use
- your own (HTML) document instead of the SlipKnot Local Home Page. After
- creating this document with either an HTML authoring tool, or your
- direct knowledge of the HTML language, save this page with a file suffix
- of ".HTM". Make sure that you try out how it looks with the
- Navigate/Display Local HTML File menu option in SlipKnot. Then you will
- be able to tell SlipKnot to bring that page up automatically in the place
- of the SlipKnot Local Home Page when SlipKnot Web is entered.
- <p>
- <b>Notes on Personal Pages:</b>
- <ul>
- <li>This feature is only available to registered SlipKnot users.
- <li><b>Despite the fact that you can replace our Local Home Page with yours,
- you should periodically display ours, because inside ours is the link to
- the SlipKnot What's New Page, which is the key to SlipKnot upgrades.</b> You can
- always do this by clicking on the icon which looks like a (shareware) house.

-
- <h3><b>Executing SlipKnot Web as an offline viewer</b></h3>
- SlipKnot Web is a program called "SNWEB.EXE" inside your \SLIPKNOT directory.
- For the sake of the example below, let's assume that your SlipKnot directory
- is C:\SLIPKNOT. You can run SlipKnot Web to view your HTML documents without
- having to launch all of SlipKnot. Let's suppose that you want to display
- the HTML file: "C:\MYHTML\ME.HTM". Here are three ways:
- <ol>
- <li>In Windows Program Manager, bring up the menu item: File/Run, and type:
- C:\SLIPKNOT\SNWEB.EXE C:\MYHTML\ME.HTM
- <li>In Windows File Manager, "Associate" files with the ".HTM" suffix with
- the program C:\SLIPKNOT\SNWEB.EXE. Then you can double-click on any ".HTM"
- file in your directory listings, and SlipKnot Web will come up and display
- that file. Be sure to close SlipKnot Web before going back to File Manager
- and asking for another file to be displayed.
- <li>If you are a Windows programmer, you can ask Windows to execute the
- SNWEB program as follows: "C:\SLIPKNOT\SNWEB.EXE filename.HTM", which will
- bring up the viewer.
- </ol>
- <p>
- <b>Note:</b> SlipKnot Web will keep track of the number of documents displayed,
- and if you are an unregistered user, it will stop after having displayed
- 200 documents.

-
- <h3><b>Viewing Web documents that are on your UNIX system</b></h3>
- If you have HTML files of your own on your UNIX system -- for instance, those
- of you who use lynx regularly may have a "lynx_bookmarks.html" file, or if
- you've received an HTML file from someone and it is in you UNIX directory --
- you can retrieve and display these documents in SlipKnot Web. Press
- Navigate/Retrieve from Internet, and simply type the name of the UNIX file
- without using the "http://" scheme. Example: If you want to display the
- lynx-maintained bookmarks file, just retrieve: lynx_bookmarks.html.
- <p>
- Any filename without a URL scheme (like: "http://" or "file://" or "gopher://")
- will be taken as a filename in your UNIX directory, and downloaded, and then,
- if it is an HTML document, will be displayed.
- <p>
- By the way, you can also use this mechanism to retrieve ordinary files from
- UNIX while you are inside SlipKnot Web, and save them accordingly. And if
- a file turns out to be something that one of your installed viewers can
- process, that viewer will be automatically called up to view the file.
