A good way to try exmh is to send a message to yourself.
Here are the steps you take to do that:
Click the Send button in the message buttons in the bottom group.
exmh opens a new window containing the template for your message.
The built-in editor, sedit,
starts out with the insert cursor positioned at the end
of the first empty header line.
Enter your user name after the To: field label.
If you want to send the message to more than one person,
use a comma to separate the names.
The Section Addressing Email has more information.
Position the insert cursor on the next header field.
You can do this a few different ways.
The most direct way is to click the first mouse button where you
want the cursor to be.
There are keyboard shortcuts, too.
If you press <Tab>, the editor takes you to the end of
the next header field.
You can also use the arrow keys or the emacs-like bindings
described in the Section Editing Keys
to move the cursor.
The next field is the Cc: field.
People listed in the Cc: field get a "courtesy" (or "carbon")
copy of the message.
By convention, the message is primarily for the people listed in
the To: field, and the people in the Cc: field are
getting the message "for information."
In this case, you can leave the Cc: field empty.
Press <Tab> to move the insert cursor to the Subject: field.
Enter a subject.
The people who receive your message will get an idea of
what the message is about from the subject, so take a moment
to think of a good one.
For this test, type "exmh test message".
Make sure the header fields To: through Subject:
are acceptable.
In particular, make sure there are no blank lines
between any of the header fields.
The mail system treats a blank line as meaning "end-of-header,"
so you don't want to prematurely end the header section.
If you have a blank line, position the insert cursor on it and
use Backspace to remove the empty line.
Position the cursor at the start of the message body.
You can use the mouse,
or you can press <Tab> twice quickly.
When using the
default MH message templates, which are shown
in the example, exmh places the
cursor right after the line of dashes.
Type in your message.
When you type in a long message, the lines wrap automatically
at word boundaries.
To get a blank line for paragraph boundaries, press <Return>.
Here's where you can see how to cut and paste when
editing your message.
The built-in editor supports several editing commands
based on the GNU Emacs key bindings.
If you select the Simple Edit menu entry under the main Bindings
menu, you bring up a dialog that lets you view and edit
the key bindings.
The Section Editing Commands
describes this dialog in more detail.
The Section Editing Keys
gives a complete listing of key bindings.
If you are happy with the message, click
the Send button at the top-right corner of the window.
The Send button turns grey, and the window disappears
once the message has been sent succesfully.
If you don't want to send the message, click the Abort button instead.
If you want to save the message draft and continue to work on it later,
click the Save&Quit button.
Section Using an Existing Message as a Template describes working on a saved draft.
Send yourself a few messages, or have a friend send you
a few test messages.
You can use these test messages to practice moving around
in a folder and deleting messages.
Make one of the messages pretty long
so you can practice scrolling through it.
Finally, send mh-mime-sample@online.oreilly.com a message.
This address is a program that will return a MIME message to you.
Put for exmh tour in the Subject: field;
any text in the body will be ignored.
The Section Reading MIME Messages
describes how to read this message.
