Extra keyboards keys on Ideapad Flex 15

Question

Hi guys! I'm having a problem with the extra keys on the Ideapad Flex 15 laptop.
The problem is with two keys, one is a Task Switcher (at least that was it function on default OS (Windows)) and Display switch (in other laptops it will be XF86Display).
When I run xev, and press both key:
Display switch key displays this:

I took this in to a shop, and two technicians tried to solve the problem to no avail. One of them did as suggested, and uninstalled the touchscreen driver under Mice and other devices, but that only disabled the mouse touchpad.  So it was reinstalled, and the driver for the touchscreen under Human Interface devices was reinstalled, but none of it helped, and I still lack the touchscreen capacity I had before.  I cannot scroll except on the side ribbon, and I cannot use the touchscreen to zoom in and out, which I could do on Windows 8 and 8.1.  So it seems there is no new Lenovo driver for the  IdeapadFlex 15 that is compatible with Windows 10.  I am told to wait and see, and to hope that Lenovo addresses this problem.  BTW, I previously had two Microsoft tech people remote control my computer to fix this, and they both failed.   I am disappointed with Microsoft and Lenovo.  Any computer that was bought within the last couple of years fitted with Windows 8 should upgrade no problem to Win 10.
