.Sh OPTIONS
.Pp
.Nm
supports the following options:
.Pp
.Fl "b key"
        specify bookmark key to open
.Pp
.Fl e
        use exiftool instead of mediainfo
.Pp
.Fl i
        start in navigate-as-you-type mode
.Pp
.Fl l
        start in light mode (fewer details)
.Pp
.Fl n
        use version compare to sort files
.Pp
.Fl "p file"
        copy (or \fIpick\fR) selection to file, or stdout if file='-'
.Pp
.Fl s
        use substring match for filters instead of regex
.Pp
.Fl S
        start in disk usage analyzer mode
.Pp
.Fl v
        show version and exit
.Pp
.Fl w
        wild mode - entries unsorted on directory load
.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. Settings work on environment variables. Please
refer to the ENVIRONMENT section below.
.Pp
Configuring
.Nm
to change to the last visited directory on quit requires shell integration in a
few easy steps. Please visit the project page (linked below) for the
instructions.
.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 used contexts are underlined
.br
- rest are unused
.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.
.Sh FILTERS
Filters support regexes by 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.
.Pp
If
.Nm
is invoked as root or the environment variable \fBNNN_SHOW_HIDDEN\fR is set the default filter will also match hidden files.
.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
In case of only one match and it's a directory, `nnn` auto selects the directory and enters it in this mode.
.br
The \fIwild mode\fR can be handy for users who use the \fInavigate-as-you-type\fR mode constantly. The entries are unsorted when the directory loads. Applying filters sort 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 copied, moved or removed using respective keyboard shortcuts.
.Pp
To list the selected files press \fIy\fR.
.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

    The path is shown in the help and configuration screen.
