.Sh DESCRIPTION
.Nm
(Noice is Not Noice) is a performance-optimized, feature-packed fork of noice (http://git.2f30.org/noice/) with seamless desktop integration, simplified navigation, \fInavigate-as-you-type\fR mode with auto select, disk usage analyzer mode, bookmarks, contexts, application launcher, familiar navigation shortcuts, subshell spawning and much more. It remains a simple and efficient file manager that stays out of your way.
.Pp
.Nm

.Ar PATH
is not specified.

.Sh CONFIGURATION
.Nm
uses \fIxdg-open\fR (on Linux) and \fIopen(1)\fR (on macOS) as the desktop opener.
.Pp
There is no configuration file. Settings work on environment variables. See ENVIRONMENT section below.
.Pp
Configuring
.Nm
to change to the last visited directory on quit requires shell integration in a
few easy steps. Look up NNN_TMPFILE in the ENVIRONMENT section below.
.Sh CONTEXTS
Contexts serve the purpose of exploring multiple directories simultaneously. 4 contexts
are available. The status of the contexts are shown in the top left corner:
.Pp
- the current context is in reverse
.br
- other active contexts are underlined
.br
- rest are inactive
.Pp
To switch to a context press the Leader key followed by the context number (1-4).
.Pp
The first time a context is entered, it copies the state of the last visited context. Each context remembers its last visited directory.
.Pp
When a context is quit, the next active context is selected. If the last active context is quit, the program quits.
.Pp
Each context can have its own directory color specified. See ENVIRONMENT section below.
.Sh FILTERS
Filters support regexes (default) to instantly (search-as-you-type) list the matching
entries in the current directory.
.Pp
Common use cases:
.Pp
(1) To list all matches starting with the filter expression, start the expression
with a '^' (caret) symbol.
.br
(2) Type '\\.mkv' to list all MKV files.
.br
(3) Use '.*' to match any character (\fIsort of\fR fuzzy search).
.Pp
There is a program option to filter entries by substring match instead of regex.
.Pp
In the \fInavigate-as-you-type\fR mode directories are opened in filter mode,
allowing continuous navigation. Works best with the \fBarrow keys\fR.
.br
When there's a unique match and it's a directory, `nnn` auto selects the directory and enters it in this mode.
.br
The \fIwild load\fR option can be extremely handy for users who use the \fInavigate-as-you-type\fR mode constantly. The entries are unsorted when the directory loads. Applying filters sorts the entries (with directories on top). Directory color is disabled in this mode.
.Sh SELECTION MODE
The absolute path of a single file can be copied to clipboard by pressing \fI^K\fR if
NNN_COPIER is set (see ENVIRONMENT section below).
.Pp
To select multiple files the selection mode should be enabled using \fI^Y\fR.
In this mode it's possible to
.Pp
(1) cherry-pick individual files one by one by pressing <kbd>^K</kbd> on each entry (works across directories and contexts); or,
.br
(2) navigate to another file in the same directory to select a range of files.
.Pp
Press \fI^Y\fR again to save the selection and exit selection mode.
.Pp
Selected files are visually indicated by a \fB+\fR.
.br
The files in the list can now be listed, copied, moved, removed, archived or linked.
.Sh ENVIRONMENT
The SHELL, EDITOR (VISUAL, if defined) and PAGER environment variables take precedence
when dealing with the !, e and p commands respectively. A single combination to arguments is supported for SHELL and PAGER.
.Pp
\fBNNN_BMS:\fR bookmark string as \fIkey_char:location\fR pairs (max 10) separated by
\fI;\fR:
.Bd -literal
    export NNN_BMS='d:~/Documents;u:/home/user/Cam Uploads;D:~/Downloads/'

    NOTE: Bookmark keys should be single-character to use them in combination with the Leader key.

.Bd -literal
    export NNN_OPENER=mimeopen

.Pp
\fBNNN_OPENER_DETACH:\fR do not block when invoking file opener.
.Bd -literal
    export NNN_OPENER_DETACH=1
.Ed
.Pp

    The path is shown in the help and configuration screen.
.Ed
.Pp
\fBNNN_SCRIPT:\fR \fIabsolute\fR path to a directory to select a script from or a single script to invoke with currently selected file name as argument 1.

.Bd -literal
    export NNN_NOTE='/home/user/.mynotes'
.Ed
.Pp
\fBNNN_TMPFILE:\fR when cd on quit is pressed, the absolute path of the current open directory is written to this file. A wrapper script can read this file and cd into it once the program quits.

    export NNN_RESTRICT_NAV_OPEN=1
