Same issue as this: VNC: pressing Shift + Tab = Tab only

I can write "A" by pressing shift+a, but shift+tab won't work. Tab be triggered without the shift key. This has been an issue since at least 16 I think when I started using the gnome variant of Ubuntu. Right now I am using PopOS 18.04 and with both tigerVNC and Real VNC Viewer (on Windows 10) I have the same issue connecting to the Vino VNC server. Without the VNC connection shift+key works as expected on both Linux and Windows.

I also tried with tiger VNC viewer on the Linux subsystem. Same result.

After spending two days with this issue I have found this thread from 2009: https://bugzilla.gnome.org/show_bug.cgi?id=353304#c21

Solution: Run in Ubuntu terminal: xmodmap -e 'keycode 23 = Tab'

EDIT: to make the fix permanent run sudo vim /usr/share/X11/xkb/symbols/pc and change the line

key <TAB> { [ Tab, ISO_Left_Tab ] };

to

key <TAB> { [ Tab ] };

After that reboot.
