我的.zshrc里绑定热键ctrl+左右键来按单词移动。
[code]
                bindkey '\e[H'    beginning-of-line      # Home
                bindkey '\e[F'    end-of-line            # End
                bindkey '\e[3~'   delete-char            # Del
                bindkey '\e[2~'   overwrite-mode         # Insert
                bindkey "^[[5C"   forward-word           # ctrl cursor right
                bindkey "^[[5D"   backward-word          # ctrl cursor left
                bindkey "^[[1;5C" forward-word           # ctrl cursor right
                bindkey "^[[1;5D" backward-word          # ctrl cursor left
[/code]

你如果只能用bash，.bashrc里面这么配置应该可以
[code]
bind '"\eOC":forward-word'
bind '"\eOD":backward-word'
[/code]
查看当前键绑定用bind -p | grep "forward-word"
热键的ESC键码因终端类型不同会不一样，你可以先Ctrl+V然后按组合热键，可以看到终端识别出的键码回显，将之填入脚本即可。
