Hey guys,

I just started remapping my keyboard using Autohotkey, and thought that some others might be interested in it too. (Especially with all these G80-2551 being sold on ebay atm...) At first I started by reading out all of the scancodes using a (apparently pretty buggy) Keyboard Hook Script. Here are the results:

Code: Select all

Function Rows (Top): Row 1(FLTR):
SC05B	SC05C	SC05D	SC063	SC064	SC065	SC066	SC067	SC068	SC069	SC06A	SC06B
Row 2:
SC03B	SC03C	SC03D	SC03E	SC03F	SC040	SC041	SC042	SC043	SC044	SC057	SC058

Function Keys on the left:		Arrow Key Cluster:
SC071	SC076							SC05A	SC149	SC151
SC072	SC045							SC14F	SC152	SC153
SC074	SC06D							SC004	SC148	SC005
SC137	SC06F							SC14B	SC147	SC14D
SC075	SC06C							SC002	SC150	SC003

As these codes appeared familiar to me, I just checked, and it's exactly the same layout as on my Terminal Emulator Boards. I was too lazy to check it with the original Terminal Board and a teensy, but AFAIR the codes a Teensy sends are NOT the same.

Now most of the keys can simply be remapped using an easy script using the following template:

Code: Select all

SCXXX::Send $resultingkey

I won't give too many details on the usage of AHK, as it is a) too complex, and b) I don't know too much about it either.

Many special keys are described here: http://www.autohotkey.com/docs/commands/Send.htm

E.g. to make the two blank buttons on the left side send the win and the menu key you would need:

Code: Select all

SC06C::Send {AppsKey}
SC075::Send {LWin}

But when I looked at the 4 keys around the arrow Keys (the 123rd to 126th keys if you will) I encountered a problem, where I would ask for the help of some more experienced AHK users: These keys send a combination of keys which looks strange to me. Due to the buggy Keyhook script I couldn't see, in which sequence the Scancodes are being sent, but these keys send the Scancode for a number key (from 1 to 4) AND an obscure "SC000". I don't know what SC000 is normally, but I'm pretty sure it's reserved for something special. I already tried "SC000&SC002::", but AHK denied to load the script, stating the Hotkey was invalid, so I doubt if it's possible to remap these keys at all.

Anyhow I hope that this helps some people out there!

Try a space between them. So.. SC000 & SC002::

Well, I tried this too... I feel like the SC000 Code is reserved for something special, and cannot be remapped.

Have you had a look at how the Neo layout is implemented in AHK? Maybe you find some pointers there:

Where is the key hook script? I'd like to do this myself.

Hell Yeah!

I finally managed to remap the 4 missing keys!

The keys sent some strange stuff like this (e.g. for the right bottom key with the Calculator on it):

Code: Select all

VK	SC	Up/Dn	Elapsed	Key
FF	000	u		0.09		ÿ
32	003	d		0.00		2
FF	000	u		0.14		ÿ
32	003	u		0.00		2

So the UP Event for Scancode 000 twice and the ordinary DOWN and UP Event for the Number. It took me a while and the help of the Guys in the AHK IRC to get the Idea to use a variable and an #If . I thought of inverting the value of the variable on every UP event on Scancode 000. After another while I discovered how to use the Scancode 000. And the result worked!

Code: Select all

Key1:=False
VKFFSC000 UP::Key1:=!Key1
#If Key1
SC002::Send 1/2
SC003::Send Calculator
SC004::Send TD=
SC005::Send Paper

Behind the SCXXX you can put the AHK command you want. In this example they just send the Description of the Key. But note that you have to put this at the end of your AHK script. Everything behind #If Key1 will be ignored if Key1 is false, which is nearly always.

And I also discovered a better solution for mapping the Windows and Apps Key.

Code: Select all

SC06C::
Send {AppsKey down}
KeyWait SC06C
Send {AppsKey up}
return
SC075::
Send {LWin down}
KeyWait VKFFSC075
Send {LWin up}
return

And btw Trent: Sorry I didn't see your question. You can simply see the scancodes using the KeybdHook. Simply create a Autohotkey Script which has "#InstallKeybdHook" on its beginning and launch it. Afterwards double click the Tray Icon and go to "View/Key History".
Push the button you want to know and press F5 afterwards.
