Long story short: I have MX master 2s mouse whose thumb button sends <ctrl><alt><tab>.
I want to remap the thumb button to <ctrl> but that does not seem to be possible because there are no supported software for linux.
Hence I would like to do the next best thing, which is to try to remap <ctrl><alt><tab> to <ctrl> and hope it works.
Is there any way to achieve what I want?
OS: Ubuntu 20.04 with Unity

It would seem you are trying to circumvent the effects of what "ctrl+alt+tab" does when you hit that mouse button (maybe frequently by accident???)...
You could, alternatively, disable what "ctrl+alt+tab" does and/or assign it to a different key sequence (which I believe is change panels?)
From the Applications menu or the panel, under Settings --> Keyboard Shortcuts
There you can disable the function it executes... or reassign it.
FYI (for others),
On MATE Desktop, that option doesn't show up in the GUI... So on the command line I had to:
gsettings set org.mate.Marco.global-keybindings switch-windows-all '<Control><Alt>9'
I just picked "9" because I knew it was harmless key sequence I would never type.
On Unity I believe the equivalent would be:
gsettings set org.gnome.desktop.wm.keybindings switch-panels "['<Control><Alt>9']"
