.TP

.PP

||||
Nail presents and acme interface for a upas/fs mailbox.
|
||||
When started, a mailbox, by default
|
||||
.IR /mail/fs/mbox ,
|
||||
is presented.
|
||||
In the message list, the tag bar commands typically affect
|
||||
the selected messsage.
|
||||
In the message and composition views, they typically apply
|
||||
to the current message.
|
||||
|
||||

|
||||
list:
|

|
||||
|

.SS Format strings
|
||||
The formatting of messages in the list view is controlled by the
|
||||
format string defined through the
|
||||
.I -f
|
||||
flag.
|
||||
The format string is composed of multiple directives: plain
|
||||
characters, which are displayed unchanged; indentation directives,
|
||||
which allows spacing based on thread depth; and messages directives,
|
||||
which display message fields.
|
||||
.PP
|
||||
Directives have the following format:
|
||||
.IP
|
||||
.B "% [flags] [width] verb
|
||||
.PP
|
||||
.IR width
|
||||
limits the number of characters displayed.
|
||||
If width is negative, text is aligned right instead of left.
|
||||
.PP
|
||||
The supported flags are:
|
||||
.PD 0
|
||||
.TP
|
||||
.B >
|
||||
Insert indentation into the start of the field. This
|
||||
does not increase the width of the field.
|
||||
|
||||

.PD 0
|

.TP
|
||||
.B "[...]
|
||||

|
||||
.PD 0
