@ddstreet Thank for the explanation. (Myself, I don't know why the keyboard behaves this way; I can imagine any option, e.g., a glitch of the keyboard firmware or hardware, an unintended bug introduced by the developers of the manufacturer, a cost-reducing design of the manufacturer, or an politically intentional (against the standard!) design of the manufacturer.) As for the zoom in/out, I meant this:

The report https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1597415 describes a similar issue for older kernels; the differences pertain to error message, error code, input..., and, opposed to #19 there, I have no Windows partitions (except /boot/efi vfat) in /etc/fstab; mine is not a dual-boot machine.
