Using Pick

[table of contents] [index]
Let's take another look at the Pick command on the Sequence menu.
(The Section Searching for Messages introduced
Pick.)
It lets you search for messages by any field in the header, any
word(s) in the body, or a combination of these.
It's a flexible and powerful way to find messages.
When you use Pick, a window like
the Figure below opens
(by default, it's on top of the main xmh window; I've moved it
to the side so you can see both).
To select messages, point to one of the boxes by a field name
and type what you want to search for.
For example, to find messages from nathan, point to the
From: box and type nathan.
Figure: Main and Pick windows
In the Figure above,
I wanted to find messages which were sent to
either the
mh-users or mh-workers mailing lists).
I pointed to the To: box and typed mh-users.
Then, I clicked the Or button next to the window; another
box opened, where I typed mh-workers.
Because I left the other boxes blank, Pick ignored those fields.
If I had filled in one (or more) of them, Pick would have
found only messages that fit all the criteria -- for instance,
if I had also put the word bug in the Search: box,
Pick would have selected only messages to mh-users
or mh-workers which contained the word "bug."
Remember that, in some cases, messages may be sent to an address via
the To: field or the cc: field.
You wouldn't want to type those addresses in the Cc: boxes of
the Figure above,
though, because the address would have to be listed
in both the To: and cc: fields to be matched.
In this case, you want the
"big -Or-" button.
By default, the Pick window creates a sequence named temp.
That sequence is normally reused each time you use Pick.
Because I want to keep this sequence for awhile, I changed its name to
mailquestions.
Sequence names can be alphabetic characters (letters) only -- if you use
an invalid name, xmh won't define the sequence; you'll see a
dialog box with an error from the MH pick command.
When I click OK, the Pick window closes.
The main window's Table of Contents title changes to
project:mailquestions, and the list shows the messages in the sequence.
There'll also be an entry on the Sequence menu for the
mailquestions sequence.
See the Figure below.
Figure: Main window after picking mailquestions sequence
When you're done looking at the sequence, you can select another
existing sequence by selecting the name on the Sequence menu,
then using Open Sequence.
The mailquestions sequence entry will remain, and MH will
"remember" the messages in the sequence.
Or, you can add and delete messages from a sequence -- see the Section
Modifying Sequences.
Pick lets you make much more complicated searches.
For example, to find messages from john to alison or
from mona to zelda (but not from john to zelda
or mona to alison), you would use the big -Or-
button at the lower-left corner of the Pick area.
This makes a duplicate of all the From:, To:, etc.
boxes below the first set and puts scrollbars on the area.
I've filled in the names.
The Figure below
shows this (I've dragged down the grip to show the important parts).
Figure: Pick window after big -Or- clicked in top area
The Pick and Skip buttons choose whether messages
should or should not match the search string you type.
All the examples so far have used the Pick buttons.
But if you click the Skip button next to a field, it tells
xmh to find messages which do not match that field.
The box with a blank field name lets you specify another header
field besides From:, To:, and so on.
For instance, to search for all messages which had the following field:
Reply-To: jerryu
in the header, you'd fill in the blank field-name box as shown
in the Figure below.
(These messages might be ones that jerryu sent from
angelac's account.)
The window in that figure would match all messages from the
angelac account that have a Reply-to: jerryu
field in the header -- except messages sent on January 24, 1993.
Figure: Example of Pick skip button
Unfortunately, the format of the date you type in the Date: box
must match the message exactly.
(The Date range: boxes don't have this problem.)
As we get closer to the year 2000, more mailers are converting from the
old two-digit year format (like 93 for 1993) to using all four digits.
So, if you can't use the Date range: boxes, it's safest
to type the date with both formats.
I did that in the Figure above.
The bottom area of the Pick window isn't used too often,
but it's good to know about.
Here are some of its features:
-
The Creating sequence: box lets you choose the sequence name
Pick should write.
It defaults to temp.
xmh will empty an existing sequence unless you tell it not to.
If you want to preserve the messages that are in the sequence and add
the new messages to it, be sure you've clicked No next to
Clear old entries from sequence?.
It's not a good idea to choose a new sequence name each time you use
Pick because you can't have more than 26 sequences defined per folder.
Sequence names must be alphabetic; uppercase and lowercase letters are distinct,
so the sequence named Temp would
be different than the one named temp.
-
The with msgs from sequence: box
tells Pick which message sequence to search for the
messages you're picking.
This is set automatically to the same sequence that was selected in
the main window before you started Pick.
Usually, you'll set this to search all messages, but a
name besides all can make the search go faster because
there'll be fewer messages to search.
-
The Date range: boxes take a starting and ending date to search.
Pick ignores messages not sent between these two dates.
Unfortunately, filling in dates doesn't make the search more
efficient, because Pick still has to search all the messages
to find what date each one was sent.
If the Date field: is empty, Pick gets the
date from the Date: field in each message header.
That's usually what you want.
But you can change it to use, say, Delivery-Date:, if your mail is
processed through the MH
slocal program.
xmh will put a horizontal scrollbar above this area if
it's too wide to fit in the window.
