.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 and presented with a sample configuration file
.Pq Pa $XDG_CONFIG_HOME/meli/config.toml
that includes 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
.Shortcut \&? general toggle_help
for 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, the left-side sidebar may be toggled with
.ShortcutPeriod ` listing toggle_menu_visibility
\&.
.Pp
Each mailbox may be viewed in 4 modes:
Plain views each mail individually, Threaded shows their thread relationship visually, Conversations collapses each thread of emails into a single entry, Compact shows one row per thread.
.Pp
If you're using a light color palette in your terminal, you should set
.Em theme = "light"
in the
.Em terminal
section of your configuration.
See
.Xr meli-themes 5
for complete documentation on user themes.
.Pp
See
.Xr meli 7
for a more detailed tutorial on using
.Nm Ns
\&.
.Sh VIEWING MAIL
Open attachments by typing their index in the attachments list and then
.ShortcutPeriod a envelope_view open_attachment
\&.
.Nm
will attempt to open text inside its pager, and other content via
.Cm xdg-open Ns
\&.
Press
.Shortcut m envelope_view open_mailcap
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
.Command save-attachment Ar INDEX Ar path-to-file
command.
.Ar INDEX
is the attachment's index in the listing.
If the path provided is a directory, the attachment is saved with its filename set to the filename in the attachment, if any.
If the 0th 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 a default search method assigned.
.Em IMAP
uses the SEARCH command,
.Em notmuch
uses libnotmuch and
.Em Maildir/mbox
performs a slow linear search.
It is advised to use a search backend on
.Em Maildir/mbox
accounts.
.Nm Ns
, if built with sqlite3, includes the ability to perform full text search on the following fields:
.Em From ,
.Em To ,
.Em Cc ,
.Em Bcc ,
.Em In-Reply-To ,
.Em References ,
.Em Subject
and
.Em 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 search_backend
to
.Em sqlite3
in the configuration file and to create the sqlite3 index issue command:
.Command index Ar ACCOUNT_NAME Ns
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@example.com and cc:me@example.com
.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 search_backend
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.
