.Sh CONFIGURATION
.Nm
uses \fIxdg-open\fR (on Linux) and \fIopen(1)\fR (on OS X) as the desktop
opener. It invokes
.Pa nlay
to run desktop search utility or screensaver. Read more on
.Pa nlay
at:
.br
.Em https://github.com/jarun/nnn/wiki/all-about-nlay
.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 FILTERS
Filters support regexes to instantly (search-as-you-type) list the matching
entries in the current directory.
.Pp
There are 3 ways to reset a filter: \fI^L\fR, a search with no matches or an
extra backspace at the filter prompt (like vi).
.Pp
Common examples: If you want to list all matches starting with the filter
expression, start the expression with a
.Pa ^
(caret) symbol. Type
.Pa \.mkv
to list all MKV files.
.Pp
If
.Nm
is invoked as root 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.
.Sh ENVIRONMENT
The SHELL, EDITOR 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_DE_FILE_MANAGER:\fR set to a desktop file manager to open the current
directory with. E.g.:
.Bd -literal
    export NNN_DE_FILE_MANAGER=thunar
.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

    echo -n $1 | xsel --clipboard --input
    -------------------------------------
.Ed
.Pp
\fBNNN_NOWAIT:\fR necessary only if nnn blocks while a file is open.
.Bd -literal
    export NNN_NOWAIT=1
.Ed
.Sh KNOWN ISSUES
If you are using urxvt you might have to set backspacekey to DEC.
