.Sh CONFIGURATION
.Nm
uses \fIxdg-open\fR (on Linux) and \fIopen(1)\fR (on OS X) 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 (aka \fItabs\fR aka \fIworkspaces\fR) 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
The key prompt understands contexts. To switch contexts press \fI^B\fR and enter 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 start directory and 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 to instantly (search-as-you-type) list the matching
entries in the current directory.
.Pp
Ways to exit filter prompt:
.Pp
(1) press \fI^L\fR to clear filter followed by \fIBksp\fR (to clear the filter symbol, like vi)
.br
  - at other prompts \fI^L\fR followed by \fIEnter\fR discards all changes and exits prompt
.br
(2) run a search with no matches and press \fIEnter\fR
.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
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.
.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 copy multiple file paths 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; or,
.br
(2) navigate to another file in the same directory to select a range of files.
.Pp
Pressing \fI^Y\fR again copies the paths and exits the selection mode. The files in the list can now
be copied, moved or removed using respective keyboard shortcuts.
.Pp
To list the file paths copied to memory 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.
.Pp
\fBNNN_BMS:\fR bookmark string as \fIkey:location\fR pairs (max 10) separated by
\fI;\fR:
.Bd -literal
    export NNN_BMS='doc:~/Documents;u:/home/user/Cam Uploads;D:~/Downloads/'
.Ed
.Pp
\fBNNN_USE_EDITOR:\fR use EDITOR (preferably CLI, fallback vi) to handle text
files.
.Bd -literal
    export NNN_USE_EDITOR=1
.Ed
.Pp
\fBNNN_IDLE_TIMEOUT:\fR set idle timeout (in seconds) to invoke terminal
screensaver.
.Pp
\fBNNN_COPIER:\fR set to a clipboard copier script. For example, on Linux:
.Bd -literal
    -------------------------------------
    #!/bin/sh

    # comment the next line to convert newlines to spaces
    IFS=
    echo -n $1 | xsel --clipboard --input
    -------------------------------------
.Ed
.br
If it's not set, by default file paths are copied to the tmp file \fBDIR/.nnncp\fR, where 'DIR' (by priority) is: \fI$HOME\fR or, \fI$TMPDIR\fR or, \fI/tmp\fR.
.Pp
\fBNNN_QUOTE_ON:\fR wrap copied paths within single quotes. Useful for pasting
names in the shell. Note that the filename is not escaped. So copying may still fail
for filenames having quote(s) in them.
.Pp
\fBNNN_SCRIPT:\fR path to a custom script to invoke with currently selected file name as argument 1.
.Bd -literal
    export NNN_SCRIPT=/usr/local/bin/nscript
.Ed
.Pp
\fBNNN_MULTISCRIPT:\fR run multiple custom scripts.
.Bd -literal
    export NNN_MULTISCRIPT=1
.Ed
.Pp
\fBNNN_SHOW_HIDDEN:\fR show hidden files.
.Bd -literal
    export NNN_SHOW_HIDDEN=1
.Ed
.Pp
\fBNNN_NO_AUTOSELECT:\fR Disable directory auto-selection in \fInavigate-as-you-type\fR mode.
.Bd -literal
    export export NNN_NO_AUTOSELECT=1
.Ed
