1. 我需要把 ubuntu 按键进行互换映射

原功能 目标功能 caps lctrl lctrl return return rctrl rctrl caps

sudo vim /usr/share/X11/xkb/keycodes/evdev

<RTRN> = 37;
<CAPS> = 105;
<LCTL> = 66;
<RCTL> = 36;

2. 我需要把 win10 的按键进行一样的互换映射，需要修改注册表，HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout 增加二进制 Scancode Map，具体值是：

00,00,00,00,00,00,00,00,05,00,00,00,1d,00,3a,00,1c,00,1d,00,
1d,e0,1c,00,3a,00,1d,e0,00,00,00,00

导出的注册表是：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,05,00,00,00,1d,00,3a,00,1c,00,1d,00,\
  1d,e0,1c,00,3a,00,1d,e0,00,00,00,00
