安装zsh以后，发现小数字键盘不能使用，可按照以下步骤添加小数字键盘的支持。

打开终端，输入

vim ~/.zshrc

拉到最下面，将以下代码复制到里面即可

# key bindings
bindkey "\e[1~" beginning-of-line
bindkey "\e[4~" end-of-line
bindkey "\e[5~" beginning-of-history
bindkey "\e[6~" end-of-history

# for rxvt
bindkey "\e[8~" end-of-line
bindkey "\e[7~" beginning-of-line
# for non RH/Debian xterm, can't hurt for RH/DEbian xterm
bindkey "\eOH" beginning-of-line
bindkey "\eOF" end-of-line
# for freebsd console
bindkey "\e[H" beginning-of-line
bindkey "\e[F" end-of-line
# completion in the middle of a line
bindkey '^i' expand-or-complete-prefix

# Fix numeric keypad  
# 0 . Enter  
bindkey -s "^[Op" "0"
bindkey -s "^[On" "."
bindkey -s "^[OM" "^M"
# 1 2 3  
bindkey -s "^[Oq" "1"
bindkey -s "^[Or" "2"
bindkey -s "^[Os" "3"
# 4 5 6  
bindkey -s "^[Ot" "4"
bindkey -s "^[Ou" "5"
bindkey -s "^[Ov" "6"
# 7 8 9  
bindkey -s "^[Ow" "7"
bindkey -s "^[Ox" "8"
bindkey -s "^[Oy" "9"
# + - * /  
bindkey -s "^[Ol" "+"
bindkey -s "^[Om" "-"
bindkey -s "^[Oj" "*"
bindkey -s "^[Oo" "/"

最后 输入source进行应用

source ~/.zshrc

小数字键盘就可以使用了
