The Mailbox Selector

	This window appears in two distinct forms. The first is when
you are selecting a mailbox to Open. The second form is used to select
a mailbox to copy/move messages from an already open mailbox. Most of
the functionality is the same, but there are a few minor differences. 
	For each mode of operation, the "convenience buttons" located
below the main menubar change, and in the copy/move mode, this window
becomes "modal", i.e. it takes over the keyboard and mouse such that
you will not be allowed to continue working in other windows until a
mailbox has been selected (or until you apply "Cancel").

	The window contains three text fields and a selection list.

Configuration:

	Every mailbox belongs to a "configuration", which determines
how to access it. This includes such things as the server name and
type of communications protocol used for transactions. You may type in
the name of a known configuration here, or use the corresponding
button to cycle through the known entries. If you enter an unknwon
configuration name, the Network Configuration Window will be invoked
to fill in the necessary information.
	In the copy/move mode of operation, the configuration needs
to be one that supports Mail. You cannot copy/move to a newsgroup.

Search Pattern:

	A search pattern to apply to the list of mailboxes to filter
the result. By default the selection mode is set to "Subscribed
Mailboxes" and the initial pattern set to "*" (ALL entries).
	If you toggle the selection mode to "All Mailboxes", this
pattern is automatically set to "%", which matches all entries in
the default directory. It is important to note the difference.
	The "All Mailboxes" mode, when applied to a "mail"
configuration, is a file selector on the mail server. The "*" pattern
matches EVERY FILE KNOWN to that server, and may take hours or days to
return, depending on the server filesystem. One connected to the
Andrew File System will list every file on every machine connected to
AFS. On a "news" server, every known newsgroup is returned. This isn't
quite as bad as for a mail server, but will still take a lengthy time
to process.
	When using this field, it is therefore important to prefix any
wildcard patterns appropriately, expecially when using "All Mailboxes".
For newsgroups, "comp.*" lists the entire contents of the "comp"
hierarchy. "comp.%" matches only those entries one level down from
"comp.", such as "comp.mail", but NOT "comp.mail.misc".
	When applied to mailboxes, "~/%" lists your home directory on
the mail server. "~/mail/*" will list every file in your personal mail
directory, including the contents of any subdirectories. "~/mail/%"
will restrict the search to the "mail" directory alone, and no
subdirectories will be processed. 
	Pressing the associated button will reset the Search Pattern
to the default for the current mode.


Mailbox Name:

	This is the name of the mailbox target for the operation you
intend to perform. Note that to copy/move to a mailbox, it must first
exist. If you just type in a name here, you should also use "Create"
from the Subscription menu to create it before selecting
Open/Copy/Move etc., or the resulting operation will fail. The button
associated with this field will sequentially select each item in the 
current list. 

The Mailbox List:

	This list is filled in when needed by opening a connection to
the server in question. You may be asked for a password at that
time. OR, you may not, depending on the server policy. INBOX, if it
exists, and matches the requested pattern, will always be first in the
list, unless your search pattern precludes it. The remaining items are
sorted alphabetically. When the program starts up, it doesn't
automatically fetch this list, because it may take some time to
process on a slow network link. In the case where you know what
mailbox name you wish to use, just type it in. Use the "Fetch" button
to go out and get the list.  When you perform a Subscription
operation, the list will be fetched and updated accordingly.


Folder Path and Mailbox Names:

	If you have defined a Mail Folder Path in your personal
preferences, you may see mailboxes referred to as "+name". The "+" is
shorthand for your folder path. It will be replaced by the program
with your folder path whenever needed. You may also refer to files in
your mail folder by naming them "+name". Files in other locations need
the full path name (or path relative to your home directory on the
server), using the server's directory separation character (which is
usually "/" on Unix systems).

Menu Items:
		Convenience Buttons:

Open
	Open the named Mailbox, using the selected Configuration. 

Scan
	This button is used mostly for newsgroups. It will open the
"selected" Mailbox (and implies a selection in the mailbox list has
been made). It will also automatically advance the selection to the
next mailbox in the list. The next time you select "Scan", the first
mailbox will be closed before the next one is opened. When you reach
the end of the list, this button will be disabled. You may alter the
current selection before using this to jump to another mailbox.

In copy/move mode the above buttons are replaced by:

Copy
	Use the selected mailbox as the target to copy the selected
messages to. You cannot copy messages to a newsgroup. 

Move
	Use the selcted mailbox as the target to move the selected
messages to. This is the same as copy except that the messages are
then marked DELETED in the original mailbox.


Fetch
	This instructs the program to fetch the desired list from the
mailbox server, using the supplied Search Pattern to filter the results. 


Dismiss/Cancel
	Close the Mailbox Selector Window. If you are performing a
copy/move, the operation will be cancelled.


			The Subscribe Menu

New Mailbox
	Create a new mailbox, using the name in the Mailbox Name
field, and located on the server defined by the Configuration
field. If this is a newsgroup, the selected name will be added to your
subscription list and no mailbox created (you cannot create new
newsgroups).

Kill Mailbox
	This destroys the mailbox name selected in the Mailbox Name
field from the server defined by the Configuration field. If this is a
newsgroup, it will merely be unsubscribed. For a mailbox, the mailbox
AND ITS CONTENTS will be removed. A dialog will allow you confirm this
decision.

Rename Mailbox
	Change the name of the selected mailbox. You cannot change the
name of a newgroup. You will be prompted for the new name. 

Subscribe Only
	This will add the currently selected mailbox to your
subscription list. It will not create it, and it is assumed the
mailbox already exists.

Unsubscribe Only
	This will remove the selected mailbox from your subscription
list, but without destroying the contents. 

Create Mailbox
	Create a new mailbox using the name given in the Mailbox Name
field, on the server defined by the Configuration field. You cannot
create a newsgroup. This will NOT be added to your subcription list.

			The Option Menu

Show All Mailboxes
	By default, the list contains only those mailboxes you have
subscribed to. This will allow you to locate other existing mailboxes
on the server which you may then subscribe to.

Show Subscribed Mailboxes
	The default. Show only items to which you have previously
subscribed.
