Custom keyboard shortcut fails to assign "search" key
Regression: problem started in Ubuntu 19.10. Reported downstream https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1861025
In the most recent version (Ubuntu 20.10) I can using the Gnome keyboard shortcuts GUI to set up a custom keyboard shortcut associated witth the "search" key, but it is useless. No matter what I do, the search key continues to give me a desktop search function. This cannot be turned off, and cannot be reassigned.
In my case, "search" is the F10 key (without Function modifier) on a Lenovo T450s.
