### Introduction
-noice is a blazing-fast terminal file browser with easy keyboard shortcuts for navigation, opening files and running tasks. noice is developed with terminal based systems in mind. However, the incredible user-friendliness and speed make it a perfect utility on modern distros. Navigate to `/usr/bin` from your regular file browser and noice to feel the difference.
+nnn is a fork of [noice](http://git.2f30.org/noice/), a blazing-fast terminal file browser with easy keyboard shortcuts for navigation, opening files and running tasks. It is developed with terminal based systems in mind. However, the incredible user-friendliness and speed make it a perfect utility on modern distros.
-The only issue with noice is hard-coded file association. There is no config file (better performance and simpler to maintain) and you have to modify the source to change associations (see [how to change file associations](#change-file-associations)). This fork solves the problem by adding the flexibility of using the default desktop opener at runtime. There are several other improvements too (see [fork-toppings](#fork-toppings)).

+.Sh NAME
+.Nm nnn
+.Nd small file browser
+.Sh SYNOPSIS
+.Nm nnn
+.Op Ar dir
+.Sh DESCRIPTION
+.Nm
+is a simple and efficient file browser that gets out of your way
+as much as possible. It was initially implemented to be controlled
+with a TV remote control.
+.Pp
+.Nm
+defaults to the current directory if
+.Ar dir
+is not specified. As an extra feature, if
+.Ar dir
+is a relative path,
+.Nm
+will not go back beyond the first component of the path using standard
+navigation key presses.
+.Pp
+.Nm
+supports both vi-like and emacs-like key bindings in the default
+configuration. The default key bindings are described below;
+their functionality is described in more detail later.
+.Pp
+.Bl -tag -width "l, [Right], [Return] or C-mXXXX" -offset indent -compact
+.It Ic k, [Up] or C-p
+Move to previous entry.
+.It Ic j, [Down] or C-n
+Move to next entry.
+.It Ic [Pgup] or C-u
+Scroll up half a page.
+.It Ic [Pgdown] or C-d
+Scroll down half a page.
+.It Ic [Home], ^ or C-a
+Move to the first entry.
+.It Ic [End], $ or C-e
+Move to the last entry.
+.It Ic l, [Right], [Return] or C-m
+Open file or enter directory.
+.It Ic h, C-h, [Left] or [Backspace]
+Back up one directory level.
+.It Ic / or &
+Change filter (see below for more information).
+.It Ic c
+Change into the given directory.
+.It Ic ~
+Change to the HOME directory.
+.It Ic \&.
+Toggle hide .dot files.
+.It Ic t
+Toggle sort by time modified.
+.It Ic C-l
+Force a redraw.
+.It Ic \&!
+Spawn a shell in current directory.
+.It Ic z
+Run the system top utility.
+.It Ic e
+Open selected entry with the vi editor.
+.It Ic p
+Open selected entry with the less pager.
+.It Ic q
+Quit.
+.El
+.Pp
+Backing up one directory level will set the cursor position at the
+directory you came out of.
+.Sh CONFIGURATION
+.Nm
+is configured by modifying
+.Pa config.h
+and recompiling the code.
+.Pp
+The file associations are specified by regexes
+matching on the currently selected filename. If a match is found the associated
+program is executed with the filename passed in as the argument. If no match
+is found the program
+.Xr less 1
+is invoked. This is useful for editing text files
+as one can use the 'v' command in
+.Xr less 1 to edit the file using the EDITOR environment variable.
+.Pp
+See the examples section below for more information.
+.Sh FILTERS
+Filters allow you to use regexes to display only the matched
+entries in the current directory view. This effectively allows
+searching through the directory tree for a particular entry.
+.Pp
+Filters do not stack on top of each other. They are applied anew
+every time.
+.Pp
+To reset the filter you can input an empty filter expression.
+.Pp
+If
+.Nm
+is invoked as root the default filter will also match hidden
+files.
+.Sh ENVIRONMENT
+The SHELL, EDITOR and PAGER environment variables take precedence
+when dealing with the !, e and p commands respectively.
+.Pp
+\fBNNN_OPENER:\fR set to your desktop environment's default
+mime opener to override all custom mime associations.
+.br
+Examples: xdg-open, gnome-open, gvfs-open.
+.Pp
+\fBNNN_FALLBACK_OPENER:\fR set to your desktop environment's default
+mime opener to use as a fallback when no association is set for a file
+type. Custom associations are listed in the EXAMPLES section below.
+.Pp
+\fBNNN_COPIER:\fR set to a clipboard copier script. For example, on Linux:
+.Bd -literal
+ #!/bin/sh
+
+ echo -n $1 | xsel --clipboard --input
+.Sh EXAMPLES
+The following example shows one possible configuration for
+file associations which is also the default if environment
+variable NNN_OPENER is not set:
+.Bd -literal
+ struct assoc assocs[] = {
+ { "\\.(c|cpp|h|txt|log)$", "vim" },
+ { "\\.pdf$", "zathura" },
+ { "\\.sh$", "sh" },
+ };
+Plain text files are opened with vim.
+.br
+Any other file types are opened with the 'xdg-open' command.
+.Ed
+.Sh KNOWN ISSUES
+If you are using urxvt you might have to set backspacekey to DEC.
+.Sh AUTHORS

-.Dt NOICE 1
-.Os
-.Sh NAME
-.Nm noice
-.Nd small file browser
-.Sh SYNOPSIS
-.Nm noice
-.Op Ar dir
-.Sh DESCRIPTION
-.Nm
-is a simple and efficient file browser that gets out of your way
-as much as possible. It was initially implemented to be controlled
-with a TV remote control.
-.Pp
-.Nm
-defaults to the current directory if
-.Ar dir
-is not specified. As an extra feature, if
-.Ar dir
-is a relative path,
-.Nm
-will not go back beyond the first component of the path using standard
-navigation key presses.
-.Pp
-.Nm
-supports both vi-like and emacs-like key bindings in the default
-configuration. The default key bindings are described below;
-their functionality is described in more detail later.
-.Pp
-.Bl -tag -width "l, [Right], [Return] or C-mXXXX" -offset indent -compact
-.It Ic k, [Up] or C-p
-Move to previous entry.
-.It Ic j, [Down] or C-n
-Move to next entry.
-.It Ic [Pgup] or C-u
-Scroll up half a page.
-.It Ic [Pgdown] or C-d
-Scroll down half a page.
-.It Ic [Home], ^ or C-a
-Move to the first entry.
-.It Ic [End], $ or C-e
-Move to the last entry.
-.It Ic l, [Right], [Return] or C-m
-Open file or enter directory.
-.It Ic h, C-h, [Left] or [Backspace]
-Back up one directory level.
-.It Ic / or &
-Change filter (see below for more information).
-.It Ic c
-Change into the given directory.
-.It Ic ~
-Change to the HOME directory.
-.It Ic \&.
-Toggle hide .dot files.
-.It Ic t
-Toggle sort by time modified.
-.It Ic C-l
-Force a redraw.
-.It Ic \&!
-Spawn a shell in current directory.
-.It Ic z
-Run the system top utility.
-.It Ic e
-Open selected entry with the vi editor.
-.It Ic p
-Open selected entry with the less pager.
-.It Ic q
-Quit.
-.El
-.Pp
-Backing up one directory level will set the cursor position at the
-directory you came out of.
-.Sh CONFIGURATION
-.Nm
-is configured by modifying
-.Pa config.h
-and recompiling the code.
-.Pp
-The file associations are specified by regexes
-matching on the currently selected filename. If a match is found the associated
-program is executed with the filename passed in as the argument. If no match
-is found the program
-.Xr less 1
-is invoked. This is useful for editing text files
-as one can use the 'v' command in
-.Xr less 1 to edit the file using the EDITOR environment variable.
-.Pp
-See the examples section below for more information.
-.Sh FILTERS
-Filters allow you to use regexes to display only the matched
-entries in the current directory view. This effectively allows
-searching through the directory tree for a particular entry.
-.Pp
-Filters do not stack on top of each other. They are applied anew
-every time.
-.Pp
-To reset the filter you can input an empty filter expression.
-.Pp
-If
-.Nm
-is invoked as root the default filter will also match hidden
-files.
-.Sh ENVIRONMENT
-The SHELL, EDITOR and PAGER environment variables take precedence
-when dealing with the !, e and p commands respectively.
-.Pp
-\fBNOICE_OPENER:\fR set to your desktop environment's default
-mime opener to override all custom mime associations.
-.br
-Examples: xdg-open, gnome-open, gvfs-open.
-.Pp
-\fBNOICE_FALLBACK_OPENER:\fR set to your desktop environment's default
-mime opener to use as a fallback when no association is set for a file
-type. Custom associations are listed in the EXAMPLES section below.
-.Sh EXAMPLES
-The following example shows one possible configuration for
-file associations which is also the default if environment
-variable NOICE_OPENER is not set:
-.Bd -literal
-struct assoc assocs[] = {
- { "\\.(c|cpp|h|txt|log)$", "vim" },
- { "\\.pdf$", "zathura" },
- { "\\.sh$", "sh" },
-};
-Plain text files are opened with vim.
-.br
-Any other file types are opened with the 'xdg-open' command.
-.Ed
-.Sh KNOWN ISSUES
-If you are using urxvt you might have to set backspacekey to DEC.
-.Sh AUTHORS
-.An Lazaros Koromilas Aq Mt lostd@2f30.org ,
-.An Dimitris Papastamos Aq Mt sin@2f30.org .
-.Pp
-** The current non-mainstream version is a modified one patched by Arun Prakash Jana <engineerarun@gmail.com>.
