.Sh DESCRIPTION
.Nm
(Nnn's 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
opens the current working directory by default if
.Ar PATH
is not specified.
.Sh KEYBINDS
.Pp
Press \fB?\fR in
.Nm
to see the list of keybinds.
.Sh OPTIONS
.Pp
.Nm
supports the following options:
.Pp
.Fl a
use access time for all operations (default: modification time)
.Pp
.Fl "b key"
specify bookmark key to open
.Pp
.Fl d
detail mode
.Pp
.Fl f
run filter as command when the prompt key is pressed
.Pp
.Fl H
show hidden files
.Pp
.Fl i
start in navigate-as-you-type mode
.Pp
.Fl n
use case-insensitive version compare to sort files
.Pp
.Fl o
open files only on Enter key
.Pp
.Fl "p file"
copy (or \fIpick\fR) selection to file, or stdout if file='-'
.Pp
.Fl r
show cp, mv progress (Linux-only, needs advcpmv; '^T' shows the progress on BSD/macOS)
.Pp
.Fl s
use substring match for filters instead of regex
.Pp
.Fl S
start in disk usage analyzer mode
.Pp
.Fl t
disable directory auto-select in navigate-as-you-type mode
.Pp
.Fl v
show version and exit
.Pp
.Fl h
show program help and exit
.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. Associated files are stored in \fB${XDG_CONFIG_HOME:-$HOME/.config}/nnn/\fR. 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 video
.br
- other active contexts are underlined
.br
- rest are inactive
.Pp
On context creation, the state of the previous context is copied. Each context remembers its last visited directory.
.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
There is a program option to execute the current filter as a command when the prompt key is pressed.
.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,
.Nm
auto selects the directory and enters it in this mode.
.Sh SELECTION
Use \fI^K\fR to select the file under the cursor.
.Pp
To select multiple files press \fI^Y\fR and enter selection mode.
In this mode it's possible to
.Pp
(1) cherry-pick individual files one by one by pressing \fI^K\fR 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
Running any operation that uses the selection OR pressing \fI^Y\fR again will save the selection and exit the selection mode.
.Pp
Press \fI^Y\fR twice to clear selection.
.Pp
Selected files are visually indicated by a \fI+\fR before the entries.
.br
The files in the list can now be listed, copied, moved, removed, archived or linked.
.br
Absolute paths of the selected files are copied to the temporary file \fB.selection\fR in config directory. The path is shown in the help and configuration screen. If \fB$NNN_COPIER\fR is set (see ENVIRONMENT section below) the file paths are also copied to the system clipboard.
.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: To go to a bookmark, press the leader key followed by the bookmark key.
.Ed
.Pp
\fBNNN_PLUG:\fR directly executable plugins as \fIkey_char:location\fR pairs (max 10) separated by
\fI;\fR:
.Bd -literal
export NNN_PLUG='o:fzy-open;p:mocplay;d:ndiff;m:nmount;t:thumb;i:mediainf'
NOTE: To run a plugin directly, press \fI:\fR followed by the plugin key.
.Ed
.Pp
\fBNNN_USE_EDITOR:\fR use VISUAL (else EDITOR, preferably CLI, fallback vi) to handle text files.
.Bd -literal
export NNN_USE_EDITOR=1
.Ed
.Pp
\fBNNN_CONTEXT_COLORS:\fR string of color codes for each context, e.g.:
.Bd -literal
export NNN_CONTEXT_COLORS='1234'
codes: 0-black, 1-red, 2-green, 3-yellow, 4-blue (default), 5-magenta, 6-cyan, 7-white
.Ed
.Pp
\fBNNN_SSHFS_OPTS:\fR pass additional options to sshfs command:
.Bd -literal
export NNN_SSHFS_OPTS='sshfs -o reconnect,idmap=user,cache_timeout=3600'
NOTE: The options must be preceded by `sshfs` and comma-separated without any space between them.
.Ed
.Pp
\fBNNN_OPENER:\fR specify a custom file opener.
.Bd -literal
export NNN_OPENER=mimeopen
.Ed
.Pp
\fBNNN_IDLE_TIMEOUT:\fR set idle timeout (in seconds) to invoke terminal locker (default: disabled).
.Pp
\fBNNN_COPIER:\fR system clipboard copier script. The project page has some sample copier scripts.
.Pp
\fBNNN_TRASH:\fR trash (instead of \fIdelete\fR) files to desktop Trash.
.Bd -literal
export NNN_TRASH=1
.Ed
.Sh KNOWN ISSUES
.Nm
may not handle keypresses correctly when used with tmux (see issue #104 for more details). Set \fBTERM=xterm-256color\fR to address it.
.Pp
Use the keybind \fI'\fR to toggle selection if you are having issues with \fI^Y\fR on *BSD or macOS. To use \fI^Y\fR, run:
.Bd -literal
stty dsusp undef
