Nook Simple Touch assigning hard keys
From nookDevs
There are four hard keys on the Nook Simple Touch. They are normally assigned to special reader application keys of forward and backward page. They may be assigned to other functions.
The configuration file is /system/usr/keylayout/TWL4030_Keypad.kl
This file contains the scancode to keycode conversion for many keys. Only four of these entries actually do anything. The mapping for the "n" button, the power button and any USB keyboards are done in separate files.
To modify this file you will have to write enable the system directory.
At the end of this file is the configuration for the four hard keys.
| Scancode | Location |
|---|---|
| 412 | Upper left |
| 407 | Upper right |
| 139 | Lower left |
| 158 | Lower right |
