    Emacs 下交换 Contorl_L 和 Caps_Lock 的小程序
    程序名： key-changer

    下载地址（含 deb, tar.gz 两种格式）：
    https://sourceforge.net/projects/emacsl ... ale-zh-cn/

    * 使用说明：
    key-changer -swap  (注意：参数 -swap 前面要有一个空格)
    即可实现Contorl_L 和 Caps_Lock 的键位互换。
    （说明：退出登陆或重新启动后，又恢复为正常键位）

    • 想恢复正常键位的方法（运行以下任意一种命令均可）：
    方法1: 再带 -swap 参数运行一次：
    • key-changer -swap

    方法2: 带 -rkey 参数运行：
    • key-changer -rkey

    方法3：退出登陆或重新启动后，又恢复为正常键位

    其它功能选项，请运行 key-changer -h 查看更多帮助

    技巧：如果为了方便玩街机模拟器游戏，或者原键盘上某个键位损坏，需要替换键位，可以查看 脚本 /usr/local/bin/key-changer 的内容，
    添加或修改功能选项即可。

    详细的键位信息，可运行 key-changer -pke (实际上是调用 xmodmap -pke)查看完整信息。

    文件内容其实就是一个 bash 脚本 /usr/local/bin/key-changer

    脚本完整内容如下：
    1. #! /bin/bash
    2. ## swap Caps_Lock and Control_L for Emacs
    3. # version 0.1, 2013-08-05
    4. # Author: Careone
    5. # require /usr/bin/xmodmap from package "x11-xserver-utils"
    7. ### defines ###
    8. VERSION="0.1"
    10. # Usage: usage
    11. # Print the usage.
    12. usage () {
    13.     cat <Usage: $0 [OPTION]
    14. Swap CapsLock and Ctrl_L for current user and current session, and
    15. run again to reset swapped keys to normal.
    17.   -swap, --swap-ctrl-capslock
    18.         swap CapsLock and Ctrl_L for current user and current session, and
    19.         run again to reset swapped keys to normal.
    20.   -rkey, --reset-keymap
    21.         restore key map for current user and current session
    23.   -pm              print modifier map (equals run "xmodmap -pm")
    24.   -pke             print keymap table as expressions (equals run "xmodmap -pke")
    26.   -V, --version    print the version information and exit
    27.   -h, --help       print this message and exit
    29. Please report bugs to Careone .
