 - Ctrl-w (in incremental search) - delete whole word
 - Ctrl-k (in incremental search) - delete whole line
 
+## Configuration
+
+`ZNT` has configuration files located in `~/.config/znt`. The files are:
+
+```
+n-aliases.conf
+n-cd.conf
+n-env.conf
+n-functions.conf
+n-history.conf
+n-kill.conf
+n-list.conf
+n-options.conf
+n-panelize.conf
+```
+
+`n-list.conf` contains main configuration variables:
+
+```zsh
+# Should the list (text, borders) be drawn in bold
+local bold=0
+
+# Main color pair (foreground/background)
+local colorpair="white/black"
+
+# Should draw the border?
+local border=1
+
+# Combinations of colors to try out with Ctrl-T and Ctrl-G
+# The last number is the bold option, 0 or 1
+local -a themes
+themes=( "white/black/1" "green/black/0" "green/black/1" "white/blue/0" "white/blue/1"
+         "magenta/black/0" "magenta/black/1" )
+```
+
+Read remaining configuration files to see what's in them. Nevertheless, configuration
+can be also set from `zshrc`. There are `5` standard `zshrc` configuration variables:
+
+```
+znt_history_active_text - underline or reverse - how should be active element highlighted
+znt_history_nlist_coloring_pattern - pattern that can be used to colorize elements
+znt_history_nlist_coloring_color - color with which to colorize
+znt_history_nlist_coloring_match_multiple - should multiple matches be colorized (0 or 1)
+znt_history_keywords (array) - search keywords activated with `Ctrl-X`
+```
+
+Above variables will work for `n-history` tool. For other tools, change `_history_` to
+e.g. `_cd_`, for the `n-cd` tool. The same works for all `8` tools.
+
+Common configuration of the tools uses variables with `_list_` in them:
+
+```
+znt_list_bold - should draw text in bold (0 or 1)
+znt_list_colorpair - main pair of colors to be used, e.g "green/black"
+znt_list_border - should draw borders around windows (0 or 1)
+znt_list_themes (array) - list of themes to try out with Ctrl-T, e.g. ( "white/black/1" "green/black/0" )
+znt_list_instant_select - should pressing enter in search mode leave tool (0 or 1)
+```

+${h2}[${rst}, ${h2}]${rst} - jump directory bookmarks in n-cd and typical signals in n-kill
+${h2}g, ${h2}G${rst} - beginning and end of the list
+${h2}/${rst} - show incremental search
+${h2}F3${rst} - show/hide incremental search
+${h2}Esc${rst} - exit incremental search, clearing filter
+${h2}Ctrl-W${rst} (in incremental search) - delete whole word
+${h2}Ctrl-K${rst} (in incremental search) - delete whole line
+${h2}Ctrl-O, ${h2}o${rst} - enter uniq mode (no duplicate lines)
+${h2}Ctrl-E, ${h2}e${rst} - edit private history (when in private history view)
+${h2}F1${rst} - (in n-history) - switch view
+${h2}F2${rst}, ${h2}Ctrl-X${rst}, ${h2}Ctrl-/${rst} - search predefined keywords (defined in config files)
+
+${h1}Configuration files${rst}
+
+Location of the files is ${h3}~/.config/znt${rst}. Skeletons are copied there
+when using ${h3}zsh-navigation-tools.plugin.zsh${rst} file (sourcing it or using
+a plugin manager). There's a main config file ${h3}n-list.conf${rst} and files
+for each tool.
+
+To have a skeleton copied again into ${h3}~/.config/znt${rst}, delete it from
+there and restart Zsh a few times (3-7 or so; there's a random check
+that optimizes startup time).
+
+${h1}Predefined search keywords${rst}
+
+Following block of code in e.g. ${h3}~/.config/znt/n-history.conf${rst} defines
+set of keywords that can be invoked (i.e. searched for) via ${h2}F2${rst}, ${h2}Ctrl-X${rst}
+or ${h2}Ctrl-/${rst}:
+
+    ${h4}# Search keywords, iterated with F2 or Ctrl-X or Ctrl-/${rst}
+    ${h2}local${rst} -a keywords
+    keywords=( ${h2}\"git\" \"vim\" \"mplayer\"${rst} )
+
+${h1}Search query rotation${rst}
+
+When searching, after pressing ${h2}Ctrl-A${rst}, words 1 2 3 will become 3 1 2, etc.
+This can be used to edit some not-last word.
+
+${h1}Fix mode${rst}
+
+Approximate matching - pressing ${h2}f${rst} or ${h2}Ctrl-F${rst} will enter "FIX" mode, in which
+1 or 2 errors are allowed in what's searched. This utilizes original Zsh
+approximate matching features and is intended to be used after entering
+search query, when a typo is discovered.
+
+${h1}Color themes${rst}
+
+Following block of code in ${h3}~/.config/znt/n-list.conf${rst} defines set of
+themes that can be browsed with ${h2}Ctrl-T${rst} and ${h2}Ctrl-G${rst}:
+
+    ${h4}# Combinations of colors to try out with Ctrl-T and Ctrl-G
+    # The last number is the bold option, 0 or 1${rst}
+    ${h2}local${rst} -a themes
+    themes=( ${h2}\"white/black/1\" \"green/black/0\" \"green/black/1\"${rst}
+             ${h2}\"white/blue/0\" \"white/blue/1\" \"magenta/black/0\"${rst}
+             ${h2}\"magenta/black/1\"${rst} )
+
+It's \"foreground/background/bold\". There's support for 256-color themes
+for Zsh > 5.2, defined like e.g.: 
+
+    themes=( ${h2}\"white/17/0\" \"10/17/1\" \"white/24/1\"${rst} )
+
+i.e. with use of numbers, from 0 to 254.
+
+${h1}Private history${rst}
+
+N-history stores what's selected in its own history file. It can be
+edited. Use ${h2}e${rst} or ${h2}Ctrl-E${rst} for that when in n-history. Your \$EDITOR will
+start. This is a way to have handy set of bookmarks prepared in private
+history's file.
+
+Private history is instantly shared among sessions.
