-## Keybindings
-
-Change input mode:
-```zsh
-bindkey -v              change to vi keymap
-bindkey -e              change to emacs keymap
-```
-
-Define key-mappings:
-```zsh
-bindkey                 list mappings in current keymap
-bindkey in-str cmd      create mapping for `in-str` to `cmd`
-bindkey -r in-str       remove binding for `in-str`
-
-# C-v <key>             dump <key> code, which can be used in `in-str`
-# zle -l                list all functions for keybindings
-# man zshzle(1)         STANDARD WIDGETS: get description of functions
-```
-
-## Completion
-
-### Installation
-
-Completion functions are provided via files and need to be placed in a location
-covered by `$fpath`. By convention the completion files are names as `_<CMD>`.
-
-A completion skeleton for the command `foo`, stored in `_foo`
-```zsh
-#compdef _foo foo
-
-function _foo() {
-	...
-}
-```
-
-Alternatively one can install a completion function explicitly by calling `compdef <FUNC> <CMD>`.
-
-### Completion Variables
-
-Following variables are available in Completion functions:
-```zsh
-$words              # array with command line in words
-$#words             # number words
-$CURRENT            # index into $words for cursor position
-$words[CURRENT-1]   # previous word (relative to cursor position)
-```
-
-### Completion Functions
-- `_describe`     simple completion, just words + description
-- `_arguments`    sophisticated completion, allow to specify actions
-
-#### Completion with [`_describe`][zsh-comp-utils]
-```zsh
-_describe MSG COMP
-```
-- `MSG` simple string with header message
-- `COMP` array of completions where each entry is `"opt:description"`
-
-```zsh
-function _foo() {
-    local -a opts
-    opts=('bla:desc for bla' 'blu:desc for blu')
-    _describe 'foo-msg' opts
-}
-compdef _foo foo
-
-foo <TAB><TAB>
- -- foo-msg --
-bla  -- desc for bla
-blu  -- desc for blu
-```
-
-#### Completion with [`_arguments`][zsh-comp-utils]
-```zsh
-_arguments SPEC [SPEC...]
-```
-where `SPEC` can have one of the following forms:
-- `OPT[DESC]:MSG:ACTION`
-- `N:MSG:ACTION`
-
-Available actions
-```zsh
-(op1 op2)   list possible matches
-->VAL       set $state=VAL and continue, `$state` can be checked later in switch case
-FUNC        call func to generate matches
-{STR}       evaluate `STR` to generate matches
-```
-
-### Example
-Skeleton to copy/paste for writing simple completions.
-
-Assume a program `foo` with the following interface:
-```zsh
-foo -c green|red|blue -s low|high -f <file> -d <dir> -h
-```
-
-The completion handler could be implemented as follows in a file called `_foo`:
-```zsh
-#compdef _foo foo
-
-function _foo_color() {
-    local colors=()
-    colors+=('green:green color')
-    colors+=('red:red color')
-    colors+=('blue:blue color')
-    _describe "color" colors
-}
-
-function _foo() {
-    _arguments                              \
-        "-c[define color]:color:->s_color"  \
-        "-s[select sound]:color:(low high)" \
-        "-f[select file]:file:_files"       \
-        "-d[select dir]:fir:_files -/"      \
-        "-h[help]"
-
-    case $state in
-        s_color) _foo_color;;
-    esac
-}
-```
