System Information
Operating system: Windows 10
Graphics card: NVidia GeForce GTX 1070

Blender Version
Broken: 2.80 25-12-2018
(example: 2.79b release)
(example: 2.80, edbf15d3c0, blender2.8, 2018-11-28, as found on the splash screen)
Worked: (optional)

Short description of error

I own a Huion NEW 1060 PLUS 8192 graphics tablet. One of my keys is mapped as SHIFT, but Blender doesn't recognize it at all. As one of the pen keys is mapped as the Middle Mouse Button.
Another key on the tablet is mapped as CTRL, another as ALT etc. and they all work with the MMB on the pen, but the SHIFT key is not recognizable to Blender. I can zoom, I can rotate, I can change views but i cannot pan nor select multiple objects. Basically, everything that is connected to the SHIFT key is dead.
Blender recognizes the keyboard SHIFT key, as well as a mapped SHIFT shortcut on the mouse, but not on the tablet.
All around the OS and in Rhino, Photoshop, Illustrator, the Shift key from my tablet is working perfectly, but inside Blender no.

Oh, and this is the first time I'm trying 2.8.
Everything works fine in 2.79.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

i have made a fix in the code of blender, but since my knowledge is limited i might have not understood some of the magic that was done with the shift buttons.
https://developer.blender.org/T59882

here is a build i made yesterday, maybe you can give it a try and let me know if the fix works for you as well.

Yes! This is the fix. Blend it! :)

I don't know if I should've done that = Close - Resolved. Correct me if I did something I shouldn't have.

@ANDhitecture its not really fixed, it just shifts the functionality from one to the other, with this change we lose the shift+numpad functionality which is not good.
I will try to do a proper fix so both is working but it will take me some time due to my inexperience. i think this should stay open for the time since the issue has not been fixed.

I didn't notice that, but yes. I just checked it.
I'm still using 2.79 primarily. But I'm hoping that all of my "work stopping" issues will be resolved sooner, so I can transfer to the beta completely.

Hey guys, can any of you teach me how to do this?

System Information
Operating system: Windows 10 Home, Version 1903
Tablet: GAOMON PD1560

Blender Version
Broken: 2.80, 2.81 Alpha abeab4fcad

Short description of error
Same error as original post shows up with Gaomon PD1560.
Tablet physical buttons work correctly in other applications, and they're all apparently functional in Blender - except "shift".

kromar's fix works.

I'm being selfish, but aren't enough people using Blender for sculpting that we can make this diff the norm?

i think trading one bug for an other is not a nice solution and im pretty sure a programmer can fix this issue. what i did is just a workaround and not a real fix unfortunately.

Hey, could anyone explain to me how to properly apply this patch on windows? I've got a local copy of blender-git but anytime I try to apply the patch with git bash it fails.
I'd really appreciate the help as this process isn't very well documented and the documentation there is is not friendly to non-programmers like myself.

I can confirm same bug still in 2.90b. My workaround for panning is to map Shift+MMB but you can map only so many combo's of Shift...

Marking this as a good first issue as fixing this is well documented in the link in my comment above and the fix would be constrained to a single file.

For anyone interested in working on this and in need of a mentor feel free to message me with questions.

Hi, I can take this, but I will need someone to test on actual hardware for me once I have a potential solution.

I've done some digging and multiple sources (including the one mentioned by @PrototypeNM1) suggest using MapVirtualKey with the flag MAPVK_VSC_TO_VK_EX to differentiate left and right shift safely, rather than attempting to make sense of the scancodes directly.
All of this being unfortunately theoretical for me at the moment, since I can't test the tablet in question. I did confirm that Shift stays held during numlock 1,2,3 (hopefully no regression to Fix #29932) at least with the AT-style keyboard that I had available.
