步驟如下：
1. 安裝Magisk
2. 將想要修改的/system檔案複製到/data/adb/modules/playstore下
3. 修改/data/adb/modules/playstore下的檔案，重新開機即可生效

如下範例是修改/system/usr/keylayout/TitanKey.kl檔案

# mkdir -p /data/adb/modules/playstore/system/usr/keylayout/
# cp /system/usr/keylayout/TitanKey.kl /data/adb/modules/playstore/system/usr/keylayout/
# vi /data/adb/modules/playstore/system/usr/keylayout/TitanKey.kl
	key 42    SHIFT_LEFT
	key 253   ALT_LEFT
	key 158   CTRL_LEFT
	key 580   ALT_RIGHT
	key 251   ALT_LEFT
	key 100   SHIFT_LEFT

# reboot
