I recently bought a new Laptop (HP Envy x360, Intel i5 10th gen.) with a synaptics precision touchpad.

I just wanted to change 2 finger tap to middle mouse button. In in the win10 settings i can only choose to set 2fingertap to right click: yes or no. On my old laptop i had a dedicated synaptics tab in the advanced setting where I could change that, however I dont have that tab on my new device.

Here is what I tried so far:

  1. reinstall drivers, install older drivers from HP and Synaptics website ... yada yada yada, nothing changed anything.

(because I thought it might be a software issue i returned the laptop. I bought the same laptop 1 month later with the new intel 11th gen., but everthing is the same and because this feature is absolutely crucial to me I continued the search for a solution)

  1. as I said on my old computer i had the synaptics settings but when i changed it accordingly it didn't work anyways so had to install a 3rd party app (twofingerscroll.exe) which fixed the problem, but this program can't be installed on my new HP.

  2. I found some synaptics programs in the Win10 store but they cant be installed either

  3. now I tried to get a solution via the registry editor (however I am not experienced). I found an article which says that windows hides the synaptics settings which can be undone in the regedit:

https://7thzero.com/blog/unlock-hidden-synaptics-touch-pad-settings-windows-10

however i dont have the ' HideTPSettings ' on my device. Also I am scared that once I have the settings, it won't work anyway like on my old computer.

  1. then I found an article where they successfully mapped 3fingertap to MMB via regedit:

Windows 10 Synaptics no Control Panel and Middle Click

I tried to adapt it to the 2fingertap, but wasn't successfull so far (also rebooting the machine after every try).

I just wanted to know if anyone can help me. I just know it must be possible because people have achieved far crazier modifications (https://www.reddit.com/r/Alienware/comments/5hyf3q/registry_hacks_to_enable_hidden_touchpad_features/) and this seems rather simple in comparison.

I am glad for any help, thanks :)

This might work:

  1. Run regedit and navigate to HKEY_CURRENT_USER\Software\Synaptics\SynTP\TouchPad...
  2. Set item 2FingerTapAction to the value of 4 (for middle button click)
  3. Set item MultiFingerTapFlags to the value of 3
  4. Reboot

Note down well the values of the above items before changing them. If the items do not exist, right-click the right part and select New > DWORD (32 bit) Value to create them.

You might also find useful the TwoFingerScroll application.

  • Thank you for your answer, Harry! I tried it, but unfortunately it still acted as RMB. I disabled the checkbox in the Win10 Touchpad settings where it says '2fingertap for RMB' and retried again, but still nothing. For the TwoFingerScroll application: as I said I used it for my last computer but on my new HP i get an error message when I try to install it (some class is not registered) Is there a way to learn about regedit and what the values are mapped to? – tri-ethylEther Jan 13 '21 at 21:12
  • I have not been able to locate any documentation about `2FingerTapAction`, and I did try. There's also no known method of intercepting the event with AutoHotKey and similar. – harrymc Jan 14 '21 at 08:55
  • I was struggling with exactly the same issue and the Synaptics Mouse Properties just disabled the option to set the 2-finger-tap as middle button. So I followed the above regedit hack and went into Synaptics > ClickPad Settings and disabled and re-enabled the two-finger tap. When I opened up the config again, the disabled combobox was set to the Middle button (pulled from the registry I guess) – davidanderle May 22 '22 at 19:02
