${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.
