.Ed
.Sh STARTING WITH meli
When launched for the first time,
.Nm
will search for its configuration directory,
.Pa $XDG_CONFIG_HOME/meli/ Ns
\&.
If it doesn't exist, you will be asked if you want to create one along with a sample configuration.
The sample configuration
.Pa $XDG_CONFIG_HOME/meli/config.toml
includes comments with the basic settings required for setting up accounts allowing you to copy and edit right away.
See
.Xr meli.conf 5
for the available configuration options.
.Pp
At any time, you may press
.Cm \&?
to show a searchable list of all available actions and shortcuts, along with every possible setting and command that your version supports.
.Pp
The main visual navigation tool is the left-side sidebar.
The menu's visibility may be toggled with
.Cm `
(shortcuts.listing:
.Ic toggle_menu_visibility Ns
).
.Pp
The view into each mailbox has 4 modes: plain, threaded, conversations and compact.
Plain views each mail indvidually, threaded shows their thread relationship visually, and conversations includes one entry per thread of emails (compact is one row per thread).
.Pp
If you're using a light color palette in your terminal, you may set
.Em theme = "light"
in the
.Em terminal
section of your configuration.
See
.Xr meli-themes 5
for complete documentation on user themes.
.Sh VIEWING MAIL
Open attachments by typing their index in the attachments list and then
.Cm a Ns
\&.
.Nm
will attempt to open text inside its pager and other content via
.Cm xdg-open Ns
\&.
Press
.Cm m
instead to use the mailcap entry for the MIME type of the attachment, if any.
See
.Sx FILES
for the location of the mailcap files and
.Xr mailcap 5
for their syntax.
You can save individual attachments with the
.Cm save-attachment Ar INDEX Ar path-to-file
where
.Ar INDEX
is the attachment's index in the listing.
If the zeroth index is provided, the entire message is saved.
If the path provided is a directory, the message is saved as an eml file with its filename set to the messages message-id.
.Sh SEARCH
Each e-mail storage backend has its default search method.
.Em IMAP
uses the SEARCH command,
.Em notmuch
uses libnotmuch and
.Em Maildir/mbox
have to do a slow linear search.
Thus it is advised to use a cache on
.Em Maildir/mbox
accounts.
.Nm Ns
, if built with sqlite3, includes the ability to perform full text search on the following fields: From, To, Cc, Bcc, In-Reply-To, References, Subject and Date.
The message body (in plain text human readable form) and the flags can also be queried.
To enable sqlite3 indexing for an account set
.Em cache_type
to
.Em sqlite3
in the configuration file and to create the sqlite3 index issue command
.Cm index Ar ACCOUNT_NAME Ns \&.
.sp
To search in the message body type your keywords without any special formatting.
To search in specific fields, prepend your search keyword with "field:" like so:
.Pp
.D1 subject:helloooo or subject:\&"call for help\&" or \&"You remind me today of a small, Mexican chihuahua.\&"
.Pp
.D1 not ((from:unrealistic and (to:complex or not "query")) or flags:seen,draft)
.Pp
.D1 alladdresses:mailing@list.tld and cc:me@domain.tld
.Pp
Boolean operators are
.Em or Ns
,
.Em and
and
.Em not
.Po
alias:
.Em \&!
.Pc
String keywords with spaces must be quoted.
Quotes should always be escaped.
.sp
.Sy Important Notice about IMAP/JMAP
.sp
To prevent downloading all your messages from your IMAP/JMAP server, don't set
.Em cache_type
to
.Em sqlite3 Ns
\&.
.Nm
will relay your queries to the IMAP server.
Expect a delay between query and response.
Sqlite3 on the contrary at reasonable mailbox sizes should have a non noticable delay.
.Sh TAGS
.Nm
supports tagging in notmuch and IMAP/JMAP backends.
Tags can be searched with the `tags:` or `flags:` prefix in a search query, and can be modified by
.Cm tag add TAG
and
.Cm tag remove TAG
(see
.Xr meli.conf 5 TAGS Ns
, settings
.Ic colors
and
.Ic ignore_tags
for how to set tag colors and tag visiblity)
.Sh COMPOSING
To send mail, press
.Cm m
while viewing the appropriate account to open a new composing tab.
To reply to a mail, press
.Cm R Ns
\&.
You may edit some of the header fields from within the view, by selecting with the arrow keys and pressing
.Cm enter
to enter
.Ar INSERT
mode.
At any time you may press
.Cm e
to launch your editor (see
.Xr meli.conf 5 COMPOSING Ns
, setting
.Ic editor_cmd
for how to select which editor to launch).
Attachments may be handled with the
.Em add-attachment Ns
,
.Em remove-attachment
commands (see below).
Finally, pressing
.Cm s
will send your message by piping it into a binary of your choosing (see
.Xr meli.conf 5 COMPOSING Ns
, setting
.Ic mailer_cmd Ns
).
To save your draft without sending it, issue command
.Cm close
and select 'save as draft'.
.Pp
With no Draft or Sent mailbox,
.Nm
tries first saving mail in your INBOX and then at any other mailbox.
On complete failure to save your draft or sent message it will be saved in your
.Em tmp
directory instead and you will be notified of its location.
.Pp
To open a draft for editing later, select your draft in the mail listing and press
.Cm e Ns
\&.
.sp
Your editor can be used in
.Nm Ns
\&'s embed terminal emulator by setting
.Ic embed
to
.Em true
in your composing settings.
When launched, your editor captures all input until it exits or stops.
To stop your editor and return to
.Nm
issue Ctrl-z and to resume editing press the
.Ic edit_mail
command again (default
.Em e Ns
).
.Sh CONTACTS
.Nm
supports two kinds of contact backends:
.sp
.Bl -enum -compact -offset indent
.It
an internal format that gets saved under
.Pa $XDG_DATA_HOME/meli/account_name/addressbook Ns
\&.
.It
vCard files (v3, v4) through the
.Ic vcard_folder
option in the account section.
The path defined as

can hold multiple vCards per file.
They are loaded read only.
