g73jh touchpad registry modifications - 2 finger scroll, 2/3 finger tap, 3 finger gesture, etc

hi everyone.

i'm new here, so if this is old news or common knowledge or whatever feel free to lock/belittle/however it works around here.

short version: i missed my 2-finger middle-click from my eee 900ha, my g73jh-x2 had pinch-zoom capability meaning multitouch capability, and i demanded the twain shall meet.

after more hours than i'd like to have spent doing this, i got all sorts of nifty junk working.

i'd like to share my findings, and am mildly curious if any bold g73jh owners (or maybe even other users of laptops with relatively recent synaptics touchpads) are daring enough to modify their registries to see if they also get new, free features.

fair warning and disclosure, etc: i seriously can't guarantee that you won't damage something irreparably because, let's face it, it's the registry and it was a bad idea to begin with. i also can't guarantee that it'll work because i looked at my toshiba laptop with a synaptics 6.2 pad and it did not have the required regkeys, and i looked at a netbook at work with a synaptics 7.2 touchpad (like the g73jh) that ALSO didn't have the requisite keys and i'm not about to start adding keys to my office's computer's registry all willy-nilly and desperado-like.

ANYWAY for the bored folks that read this far, i am proud to present: some stuff.

(this assumes you're all still using windows 7 x64 and familiar with regedit and whatever.)

the following keys have a dword key called "Visibility" - change the value of this key to 0 to enable the function in the synaptics settings in the mouse control panel applet.

HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\2Scrolling\2Two-Finger Scrolling
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\4Rotating
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\4TwistRotate\2RotationAngleList
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\4TwistRotate\2RotationText
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\8Application Gestures
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\8Application Gestures\1Three Fingers Down
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\8Application Gestures\2Three-Finger Flick
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\8Application Gestures\2Three-Finger Flick\Enable Three-Finger Horizontal Flick
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\8Application Gestures\2Three-Finger Flick\Enable Three-Finger Vertical Flick
HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\8Application Gestures\3Palm On Pad

(note: i have not had luck enabling palm-on-pad, nor have i even tried rotation angle list, rotation text, or the 3-finger h/v flick settings since i found those entries after dumping the entire HKLM\SW\Synaptics keystore)

to enable 2-finger and 3-finger tap for middle- and right-click, navigate to:

HKEY_USERS\ [user SID here]\Software\Synaptics\SynTP\TouchPadPS2_3

(to find user SID, use psgetsid)

find subkey 2FingerTapAction and give it a value of 4 for middle-click, 2 for right-click. configure 3FingerTapAction in the same fashion. i prefer 2-finger middle, 3-finger right, but that's completely irrelevant.

at this point, simply disable and enable your touchpad (you can do this in the synaptics tab of the mouse control panel applet) or just reboot. hopefully you should have new functionality that was clearly there all along.

good luck, hope it works for you guys like it did for me

 

Wow....i just discovered the pinch zoom capability. Interesting.

Is there anyway to get a display of the zoom level? Or a keystroke to get it back to the default level?

Thanks.

 

i think that'd actually be more of an application-level thing; the touchpad just emulates an app's built-in zoom function if it exists. like in firefox, if you pinch-zoom in really hard and then press ctrl-0 it zooms back to 100%.

 

wow, cool, I'll have to check this out when I get some free time! Thanks for the info, and welcome to the boards!!

 

Ok....gotcha.

How about if I'm like on the desktop. Ctrl-0 doesn't seem to work.

Any ideas?

Thanks.

 

my pleasure, glad to be here this place literally saved my g73 from going back to micro center once i stumbled upon the creative-drivers-are-bad thread.

 

nope, ctrl-0 is firefox-specific.

...you can zoom the desktop?



.....HOLY CRAP

haha, thanks, now my icons are giant and misplaced!

[edit, google]

okay, yeah, that needs to be reset pronto. right-click desktop, view, medium icons brings me back to normal.

 

Lol......yup!!!!!

Now you see why I was asking for I way to get back to a default setting.

Haha.........

 

Ok great....that works!

Thanks!!!

 

You could just install Synaptics Drivers, everything you posted is supported in the driver application.

 

...touché, i concede, but why install when the features are already there? where's the fun?

(truth be told, i had looked at the scrybe suite and it did look like it had the capability of the features i was looking for but i couldn't find definitive information regarding its ability to take customization on events like 3-finger tap.)

 

Welcome to the forums zero01101.

Yeah, for a second there I thought I had only imagined the Synaptics settings.
