2. Editing Input Fields

2.1. Introduction

+You can always type “?” in any menu to display the current bindings. +

+The first thing you need to do is invoke Mutt, simply by typing mutt +at the command line. There are various command-line options, see +either the Mutt man page or the reference. +

1. Core Concepts

+Mutt is a text-based application which interacts with users through +different menus which are mostly line-/entry-based or page-based. A +line-based menu is the so-called “index” menu (listing all messages of +the currently opened folder) or the “alias” menu (allowing you to +select recipients from a list). Examples for page-based menus are the +“pager” (showing one message at a time) or the “help” menu listing +all available key bindings. +

+The user interface consists of a context sensitive help line at the top, +the menu's contents followed by a context sensitive status line and +finally the command line. The command line is used to display +informational and error messages as well as for prompts and for entering +interactive commands. +

+Mutt is configured through variables which, if the user wants to +permanently use a non-default value, are written to configuration +files. Mutt supports a rich config file syntax to make even complex +configuration files readable and commentable. +

+Because Mutt allows for customizing almost all key bindings, there are +so-called “functions” which can be executed manually (using the +command line) or in macros. Macros allow the user to bind a sequence of +commands to a single key or a short key sequence instead of repeating a +sequence of actions over and over. +

+Many commands (such as saving or copying a message to another folder) +can be applied to a single message or a set of messages (so-called +“tagged” messages). To help selecting messages, Mutt provides a rich +set of message patterns (such as recipients, sender, body contents, date +sent/received, etc.) which can be combined into complex expressions +using the boolean and and or +operations as well as negating. These patterns can also be used to (for +example) search for messages or to limit the index to show only matching +messages. +

+Mutt supports a “hook” concept which allows the user to execute +arbitrary configuration commands and functions in certain situations +such as entering a folder, starting a new message or replying to an +existing one. These hooks can be used to highly customize Mutt's +behaviour including managing multiple identities, customizing the +display for a folder or even implementing auto-archiving based on a +per-folder basis and much more. +

+Besides an interactive mode, Mutt can also be used as a command-line +tool only send messages. It also supports a +mailx(1)-compatible interface, see Table 9.1, “Command line options” for a complete list of command-line +options. +

2. Screens and Menus

2.1. Index

+The index is the screen that you usually see first when you start +Mutt. It gives an overview over your emails in the currently opened +mailbox. By default, this is your system mailbox. The information you +see in the index is a list of emails, each with its number on the left, +its flags (new email, important email, email that has been forwarded or +replied to, tagged email, ...), the date when email was sent, its +sender, the email size, and the subject. Additionally, the index also +shows thread hierarchies: when you reply to an email, and the other +person replies back, you can see the other's person email in a +"sub-tree" below. This is especially useful for personal email between +a group of people or when you've subscribed to mailing lists. +

2.2. Pager

+The pager is responsible for showing the email content. On the top of +the pager you have an overview over the most important email headers +like the sender, the recipient, the subject, and much more +information. How much information you actually see depends on your +configuration, which we'll describe below. +

+Below the headers, you see the email body which usually contains the +message. If the email contains any attachments, you will see more +information about them below the email body, or, if the attachments are +text files, you can view them directly in the pager. +

+To give the user a good overview, it is possible to configure Mutt to +show different things in the pager with different colors. Virtually +everything that can be described with a regular expression can be +colored, e.g. URLs, email addresses or smileys. +

2.3. File Browser

+The file browser is the interface to the local or remote file +system. When selecting a mailbox to open, the browser allows custom +sorting of items, limiting the items shown by a regular expression and a +freely adjustable format of what to display in which way. It also allows +for easy navigation through the file system when selecting file(s) to +attach to a message, select multiple files to attach and many more. +

2.4. Help

+The help screen is meant to offer a quick help to the user. It lists the +current configuration of key bindings and their associated commands +including a short description, and currently unbound functions that +still need to be associated with a key binding (or alternatively, they +can be called via the Mutt command prompt). +

2.5. Compose Menu

+The compose menu features a split screen containing the information +which really matter before actually sending a message by mail: who gets +the message as what (recipients and who gets what kind of +copy). Additionally, users may set security options like deciding +whether to sign, encrypt or sign and encrypt a message with/for what +keys. Also, it's used to attach messages, to re-edit any attachment +including the message itself. +

2.6. Alias Menu

+The alias menu is used to help users finding the recipients of +messages. For users who need to contact many people, there's no need to +remember addresses or names completely because it allows for searching, +too. The alias mechanism and thus the alias menu also features grouping +several addresses by a shorter nickname, the actual alias, so that users +don't have to select each single recipient manually. +

2.7. Attachment Menu

+As will be later discussed in detail, Mutt features a good and stable +MIME implementation, that is, it supports sending and receiving messages +of arbitrary MIME types. The attachment menu displays a message's +structure in detail: what content parts are attached to which parent +part (which gives a true tree structure), which type is of what type and +what size. Single parts may saved, deleted or modified to offer great +and easy access to message's internals. +

3. Moving Around in Menus

+The most important navigation keys common to line- or entry-based menus +are shown in Table 2.1, “Most common navigation keys in entry-based menus” and in +Table 2.2, “Most common navigation keys in page-based menus” for page-based menus. +

You can remap the editor functions using the -bind command. For example, to make -the Delete key delete the character in front of -the cursor rather than under, you could use +bind command. For example, to make +the <Delete> key delete the character in front of +the cursor rather than under, you could use:

 bind editor <delete> backspace
-

2.2. History

-The number of items in the built-in editor's history is controlled by -the $history variable. You may -cycle through them at an editor prompt by using the -history-up and/or history-down -commands. +

4.2. History

+Mutt maintains a history for the built-in editor. The number of items +is controlled by the $history +variable and can be made persistent using an external file specified +using $history_file. +You may cycle through them at an editor prompt by using the +<history-up> and/or +<history-down> commands. But notice that Mutt +does not remember the currently entered text, it only cycles through +history and wraps around at the end or beginning.

Mutt maintains several distinct history lists, one for each of the following categories: -

-

  • muttrc commands

  • addresses and aliases

  • shell commands

  • filenames

  • patterns

  • everything else

-

-Mutt automatically filters out repeated items from the history. It +

  • .muttrc commands

  • addresses and aliases

  • shell commands

  • filenames

  • patterns

  • everything else

+Mutt automatically filters out consecutively repeated items from the history. It also mimics the behavior of some shells by ignoring items starting -with a space. -

-The latter feature can be useful in macros to not clobber the history's -valuable entries with unwanted entries. -

5. Reading Mail

Similar to many other mail clients, there are two modes in which mail is -read in Mutt. The first is the index of messages in the mailbox, which is -called the ``index'' in Mutt. The second mode is the display of the -message contents. This is called the ``pager.'' +read in Mutt. The first is a list of messages in the mailbox, which is +called the “index” menu in Mutt. The second mode is the display of the +message contents. This is called the “pager.”

+In addition to key bindings in Table 2.7, “Most common pager keys”, +many of the functions from the index menu are also available in +the pager, such as <delete-message> or <copy-message> +(this is one advantage over using an external pager to view messages).

Also, the internal pager supports a couple other advanced features. For -one, it will accept and translate the ``standard'' nroff sequences for +one, it will accept and translate the “standard” nroff sequences for bold and underline. These sequences are a series of either the letter, -backspace (^H), the letter again for bold or the letter, backspace, -``_'' for denoting underline.

If -not, you can use the bold and underline color -objects to specify a color or mono attribute for them. +not, you can use the bold and underline color +objects to specify a color or mono attribute for them.

Additionally, the internal pager supports the ANSI escape sequences for character attributes. Mutt translates them into the correct color and -character settings. The sequences Mutt supports are -'\e[Ps;Ps;..Ps;m' +character settings. The sequences Mutt supports are: +

+\e[Ps;Ps;..Ps;m
+

where Ps can be one of the codes shown in -Table 2.5, “ANSI escape sequences”. -

+So-called “threads” provide a hierarchy of messages where +replies are linked to their parent message(s). This organizational form +is extremely useful in mailing lists where different parts of the +discussion diverge. Mutt displays threads as a tree structure. +

+In Mutt, when a mailbox is sorted +by threads, there are a few additional functions +available in the index +and pager modes as shown in +Table 2.10, “Most common thread mode keys”. +

+Collapsing a thread displays only the first message in the thread and hides the others. This is useful when threads contain so many messages that you can only see a handful of threads on -the screen. See %M in $index_format. -For example, you could use "%?M?(#%03M)&(%4l)?" in $index_format to optionally -display the number of hidden messages if the thread is collapsed. -

+Technically, every reply should contain a list of its parent messages in +the thread tree, but not all do. In these cases, Mutt groups them by +subject which can be controlled using the +$strict_threads variable. +

5.4. Miscellaneous Functions

+In addition, the index and pager +menus have these interesting functions: +

+<create-alias> (default: a) +

Creates a new alias based upon the current message (or prompts for a -new one). Once editing is complete, an alias -command is added to the file specified by the $alias_file variable for future use. Note: -Specifying an $alias_file -does not add the aliases specified there-in, you must also source the file. -

+<edit> (default: e) +

+This command (available in the index and pager) allows you to edit the raw current message as it's present in the mail folder. After you have finished editing, the changed message will be appended to the current folder, and the original message will be -marked for deletion. -

-edit-type - -(default: ^E on the attachment menu, and in the pager and index menus; ^T on the -compose menu) -

+marked for deletion; if the message is unchanged it won't be replaced. +

+<edit-type> (default: +^E on the attachment menu, and in the pager and index menus; +^T on the compose menu) +

You can also attach files to your message by specifying - -Attach: filename [ description ] - -where filename is the file to attach and description is an -optional string to use as the description of the attached file. -

-When replying to messages, if you remove the In-Reply-To: field from -the header field, Mutt will not generate a References: field, which -allows you to create a new message thread. -

-Also see $edit_headers. -

4.2. Using Mutt with PGP

-If you want to use PGP, you can specify -

-Pgp: [ E | S | S<id> ] -

-``E'' encrypts, ``S'' signs and -``S<id>'' signs with the given key, setting $pgp_sign_as permanently. +Attach: filename +[ description ]

-If you have told mutt to PGP encrypt a message, it will guide you +where filename is the file to attach and description is an +optional string to use as the description of the attached file. Spaces +in filenames have to be escaped using backslash (“\”). +The file can be removed as well as more added from the compose menu. +

6.2.3. Pgp: Pseudo Header

+If you want to use PGP, you can specify +

+Pgp: [ E | S | S<id> ] + +

+“E” selects encryption, “S” selects signing and +“S<id>” selects signing with the given key, setting +$pgp_sign_as +permanently. The selection can later be changed in the compose menu. +

6.2.4. In-Reply-To: Header

+When replying to messages, the In-Reply-To: header contains the +Message-Id of the message(s) you reply to. If you remove or modify its value, Mutt will not generate a +References: field, which allows you to create a new message thread, for example +to create a new message to a mailing list without having to enter the mailing list's address. +

4.3. Sending anonymous messages via mixmaster.

-You may also have configured mutt to co-operate with Mixmaster, an -anonymous remailer. Mixmaster permits you to send your messages -anonymously using a chain of remailers. Mixmaster support in mutt is for -mixmaster version 2.04 (beta 45 appears to be the latest) and 2.03. -It does not support earlier versions or the later so-called version 3 betas, -of which the latest appears to be called 2.9b23. -

-To use it, you'll have to obey certain restrictions. Most -important, you cannot use the Cc and Bcc headers. To tell -Mutt to use mixmaster, you have to select a remailer chain, using -the mix function on the compose menu. -

-The chain selection screen is divided into two parts. In the -(larger) upper part, you get a list of remailers you may use. In -the lower part, you see the currently selected chain of remailers. -

-You can navigate in the chain using the chain-prev and -chain-next functions, which are by default bound to the left -and right arrows and to the h and l keys (think vi -keyboard bindings). To insert a remailer at the current chain -position, use the insert function. To append a remailer behind -the current chain position, use select-entry or append. -You can also delete entries from the chain, using the corresponding -function. Finally, to abandon your changes, leave the menu, or -accept them pressing (by default) the Return key. -

-Note that different remailers do have different capabilities, -indicated in the %c entry of the remailer menu lines (see -$mix_entry_format). Most important is -the ``middleman'' capability, indicated by a capital ``M'': This -means that the remailer in question cannot be used as the final -element of a chain, but will only forward messages to other -mixmaster remailers. For details on the other capabilities, please -have a look at the mixmaster documentation. -
