Fn Keys Mode:
I've implemented this feature in order to simulate the Fn key functions of Apple for the notebooks which has real Fn keys not working and also to provide/improve the keyboard experience close to Apple keyboard. There are three modes in this feature.
They are:

Note: In version 3.0.2 (or) lesser, ApplePS2Keyboard kext is found inside the ApplePS2Controller kext. From v3.3, ApplePS2Keyboard is located inside ApplePS2ElanTouchpad and From v4.2 its in ApplePS2SmartTouchpad kext.

Mode 1

  • works without Fn key press and has Apple keyboard Fn key Mappings by default
  • It overrides the regular function keys(F1 - F12) with Fn keys, so to access those regular function keys you need to Hold "Shift + Caps" and press the respective Function key to access.
  • uses the Fn key mapping values from the plist entry "Fn Keys Mode 1"
  • you can change these mappings as you like by using the allowed keys and editing the plist file "ApplePS2Keyboard.kext/Contents/Info.plist" at the section "IOKitPersonalities->ApplePS2Keyboard->Fn keys Mode 1"

Mode 2

  • works using the Context menu key (or Hold "Shift + Caps") as Fn key and has my custom Fn key mappings
  • uses the Fn key mapping values from the plist entry "Fn Keys Mode 2"
  • you can also change these mappings as you like by using the allowed keys and editing the plist file "ApplePS2Keyboard.kext/Contents/Info.plist" at the section "IOKitPersonalities->ApplePS2Keyboard->Fn keys Mode 2".

Mode 3

  • works using the Context menu key (or Hold "Shift + Caps") as Fn key but has Fn key mapping of the Notebook vendor
  • uses the Fn key mapping used by the notebook vendor like Dell, Samsung, Acer and Asus.
  • for vendor mapping you need to edit the plist entry "Fn keys Layout" to the vendor values explained below.

 

Allowed vendor values for the Fn keys Layout:
'NONE' clears the mapping and makes the mode like disabled. I meant this value to provide vendor mapping of the Fn keys positions in Fn key mode 3 and fix some of the minor issues of Fn keys in my driver for few notebooks, because there are some scan codes used by Fn keys which are getting conflicts in ADB-scan code mapping due to each vendor doing different functions for the same scan code.

  • ASUS
  • ACER
  • DELL
  • SAMSUNG
  • MSI
  • GIGABYTE
  • LENOVO
  • NONE

 

Allowed key values for mapping the Fn key functions are:

  • F1 - F12, Pause, ArrowDown, ArrowUp, ArrowLeft and ArrowRight.
  • Enter the value "disable" in plist for disabling the Fn key mapping you don't want.

You can enable/disable this feature by editing the plist entry "Fn keys Mode" to the below values:

  • 0 - to disable Fn keys mode
  • 1 - 3 - each mode works like I've explained above

 

 

Use Right context menu key 8744268475_8a6afa765b_t.jpg (or) Hold "Shift + Caps" for mode 2

Keyboard layout ID:
This is only meant for ISO keyboard which needs to be detected using an ISO keyboard layout for the some keys to work. This is optional and is not needed for ANSI/Japanese keyboards, but you can use if you want the keyboard to be detected with an Apple keyboard layout. Default Keyboard type is set to Cosmo layout for ISO, PS2 layout Type for ANSI.
 

To configure keyboard layout id, enter the keyboard id decimal value at the plist entry "IOKitPersonalities->ApplePS2Keyboard->Keyboard type(ID)" from the plist file "info.plist" inside the AppplePS2Keyboard kext.     

 

Keyboard ID(0xXX)  /* Comments */

 

0x03  /* Unknown ANSI keyboard */

0x1B  /* Default Apple PS2 Controller ANSI keyboard */

0x2F  /* Apple M89 Wired (ISO) Keyboard */

0x2C  /* Apple M90 Wireless (ISO) Keyboard */

0xC6  /* Gestalt Cosmo USB Domestic (ANSI) Keyboard */

0xC7  /* Cosmo USB International (ISO) Keyboard */

0xC8  /* Cosmo USB Japanese (JIS) Keyboard */

0xCC  /* Andy USB Keyboard Domestic (ANSI) Keyboard */

0xCD  /* Andy USB Keyboard International (ISO) Keyboard */

Touchpad Features shortcuts:

 

I've added few keyboard shortcuts shortcuts for enabling/disabling some of the touchpad features. This is can be triggered using Left Shift, Caps Lock and a character key which represents the feature.

 

Its done like this: Hold Left Shift + Caps Lock and press "Feature Character"

NOTE: You need to Hold Left shift first then Hold Caps Lock next and finally press the character.

 

This will make caps lock LED to blink (or) pointer moving a bit up/down for touchpad features to indicate its been triggered.

 

For Auto scroll - 'A'

For Inertial scroll - 'I'

For Continuous scroll - 'C'

For Edge scroll - 'S'

For Zoom - 'Z'

For Rotate - 'R'

For Edge swipe - 'E'

For Three finger swipes - 'T'

For Four finger swipes - 'M'

For Fn keys mode - 'F'

For ALT and Windows keys swap - 'K'

For Extended functions - 'X'

For finer brightness control toggle - 'B'

For finger volume control toggle - 'V'
