Some notes on retrieving and saving sources (from the directory of servers,
or from the help query):
When you retrieve a source you will see the source description form in

simply use the \"S\" command in the results window, or the standard
Emacs save-file function (control-x control-s, or M-x save-file). If
you use the save-file function, be sure to add the .src suffix so the
interface will recognize this as a source. The \"S\" function will add
the suffix for you.

now see a typical WAIS display. Let me first tell you that you can scroll
this window by pressing the space bar and the Delete key, in case you can't
see it all.
There are five parts to this display:
1. the Search words
2. the Sources to search
3. some documents that might be similar to your intended document
4. the Resulting documents from the search
5. a document, in this case, this message.
You can now use this Question to ask further questions, or you might wish
to create some questions of your own (they don't all have to be the 'Quick'
question).
The most useful keystrokes for using WAISQ mode are (case is important!):
<space>: scroll the text in the other window up
<del>: scroll the text in the other window down
k: switches you to the search word window
e,f,v: view the current result document in a window like this one.
a: add the current document to the relevant documents list
d: delete all the relevant documents
A: capital A adds a new source
D: captial D deletes all the sources.
g,RET: perform the query.
C-l: rebuild the display, removing the document view window.
s: select a new Question
q: quit out of this question, and bury it.
Q: capital Q quits out of this question, and kill all its buffers.
?: describe waisq-mode shows all new keystrokes associated with
WAISQ mode.
You really shouldn't have to use C-x o to switch to other windows, but if
you do, you should go back to the result-documents window and press C-l to
rebuild the display.")
