%general%
X
X      IF ALL ELSE FAILS, READ THE DIRECTIONS!
X
This famous  quote applies here more  than ever. If
you are unfamiliar with Mushview, you should get
yourself acquainted with it by choosing HELP options
in menu items. If you get frustrated or confused
about how to use or run a command, or if you want to
know how something works or get to know quick shortcuts
in achieving tasks, it is advisable to look at the
Help option available with some items.
%%
X
%help%
Help was designed for users to get help from all commands
and options.  The last item in many menus is a "help"
choice.  You will get an appropriate help message describing
what you can do at the position you are in on the Mushview
window.
X
If a help message isn't much help, it may be more helpful to
reference a different help item which describes in more detail
what you want to know.  For example, reading the help for
"folder" will help you better understand the method in which
mail messages are stored than it would if you had read the help
message for "save" first.
%%
X
%mouse%
The mouse is an image (cursor) which moves across the screen. Its
position indicates which window is to receive input when you type
or click a mouse button.
X
The mouse may take upon different images which indicate various
things. When the image looks like a "coffee cup", Mushview is in
the process of doing something, like sending mail, or reading in
new mail.  In this event, you should wait till the cursor returns
to its normal state before attempting to do anything else. Go get
some coffee.
X
When in the Header Window, the cursor will look like the mouse
device that you hold with the buttons flashing on and off.  This
is to remind you that you can use each button to do different tasks.
Using the RIGHT mouse button gives you a menu of options to do for
the message under the mouse.
%%
X
%respond%
This item responds to mail in 4 ways.
In all cases, at least one recipient of your message will be the
sender of the message you are responding to. If a subject was in
the author's letter, then it will be used as your subject.
X
The first and most used method of response is to the author of the
message only.  Selecting this item with the LEFT mouse button will
use this method for responding to mail.
X
If you want to include a copy of the author's message, then choose
the menu item which  says to include the message.  If you wish for
all the recipients of the message to receive a copy of your reply,
then choosing the third item will include them.
X
The fourth menu item will mail to the author and everyone listed on
the To and Cc lines of the message, and include the message you are
responding to in your text.
X
In such cases where you include the message you are responding to,
the included message will be indented by "> " to identify it from
your message. If you would like to have a string other than the
default used, then set the appropriate option to whatever you would
prefer by selecting the "Opts" item, moving the mouse on top of the
string, "indent-str", selecting the LEFT mouse button and typing the
desired string.
%%
X
%delete%
You may  delete or undelete  messages with this item.
When using the LEFT mouse button, you will delete the
current message (HIGHLIGHTED in the headers' window).
Otherwise, you may select the menu item for undelete.
X
You may  delete or undelete a  "range" of messages by
typing the range in the Header Window.
X
For help on valid  message ranges, select the menu in
the area  marked "range" in the  Header Panel Window.
%%
X
%folder%
Your "folder" is a place to keep all your individual messages. Usually,
if you are a heavy mail user, you would organize your mail in such a
way in which related mail would be saved together in one folder.   You
create folders simply by saving mail to a filename.  Additional mail
can  be saved to those files in the same way.  To manipulate messages
in folders,  you "change folders" to the folder you wish to access
using the folder item.   Since it may occur that you switch  back and
forth  between two folders, you may use the previous  folder menu item
which updates changes  made to the current folder and  changes your
folder to the one previous to  the current.
X
You may also select  the exact name of the  folder you wish to access
by selecting  the left  mouse button on the "folder"  item and TYPING
the exact  name of the folder  you wish to access.  The "pathname" to
the folder may start with a tilde (~) indicating your home directory.
Or, it may  contain a plus sign before the  name indicating your Mail
directory (+reports, for example).  Alternatively, you  can type  '%'
to access your system Mailbox, the place where all your mail is first
delivered.  And finally, you can type '#' to indicate  the previously
accessed folder.
%%
X
%save%
You may save messages in  two ways. The most commonly used method is to
save messages to  your mailbox folder  ("mbox") in your home directory.
If you use mail very frequently and save large amounts of mail, you can
save messages to other folders for better organization.
X
Usually, when messages are saved, mushtool  marks them for deletion for
the next update.  If you don't want to have saved messages deleted, you
must undelete them or set the variable "keepsave" in the options screen.
X
There is a text item  in the Main Panel Window which allows you to type
the  name of the file to save a message.  Type the filename and then
select the LEFT mouse button over the "Save" item.  If there is no
filename specified, then messages are saved to your mbox file.
X
You may also choose a folder name by selecting the RIGHT mouse button
over the "Save" item and choosing from the menu of files displayed.
X
You can specify a range, or group of messages to save by typing a range
in the  Header Panel Window.  If there is a  message list in that panel
item, then the range of messages specified there will be saved. If not,
the current message will be saved.
X
For additional information, see the help option for Folders.
%%
X
%quit%
There are various ways in which you may be finished with Mushview.
The most commonly used method  is to simply "close" the tool to an
iconic form. This means that you haven't really quit, but you have
merely put it on "hold" till later.  It will become an icon on the
side or corner of the screen and appear to sit and do nothing.  To
close the tool to icon form, there are two methods which have will
have two different effects.
X
The first method is to select  this panel item with the left mouse
button.  This  will update your current  folder (deleting messages
marked for deletion) and close the tool.  The second method  is to
use the tool manager around the perimeter of the window and select
"close".  This will close the tool without updating your mailfile.
X
Whenever Mushview is  in the "closed"  state, it  periodically
checks your mail and updates your folder with the  new mail. While
Mushview is in iconic form, it will display the number of messages
you have in the current folder.
X
There are two equally similar methods of exiting  Mushview, rather
than just closing to an icon:  you may select the second menu item
in the menu given by this panel item or you may use the tool mana-
ger "quit" item.
X
Using the tool manager's quit will exit the tool without updating
your folder whereas the panel item's menu selection will have the
Mushview prompt you whether to update the current folder or not.
%%
X
%update%
This item will update the current folder you are using.  Changes are
updated to the folder; that is, deleted mail is removed and all other
mail is copied back to the folder unless otherwise specified. See the
help in "folder" for more information on folders.
X
If new mail has arrived, it will incorporate it. Otherwise, new mail
is incorporated every two minutes or so, if some comes in.
%%
X
%headers%
The message headers are displayed in their own separate window.
The "current" message is usually displayed in either BOLD or
REVERSE text. This "highlighted" message is the one which is
displayed at the bottom, larger window. In the message window,
each message is displayed in the following format:
the message number is displayed first; if it is the "current"
message, then there is a '>' sign.
The next character is the 'status' character:
X    'N' -- New (and unread)
X    'U' -- not new, but still Unread
X    '*' -- delete messages (set show_deleted)
X    'P' -- preserve in spoolfile.
X    'O' -- Old message which has also been Read.
If there is just a space (no character), the message is new, but
you've already read it. You should explicitly save or delete these.
X
Following that is the Author of the message and/or all or part of
his network address and login name.  Following that is the number
of lines the message is. In quotes is all or part of the "Subject"
(if one was specified).
X
To read a message, select either the READ item in the main panel
subwindow or move the mouse over the message header you want to read
and press the LEFT mouse button. Or, the MIDDLE mouse button will
delete that message. Choosing the RIGHT mouse button will give you
SHAR_EOF
