Keyboard shortcuts to bring up the keyboard shortcuts app

[MR ZenWiz]

I have been blessed (?) with a new work environment that uses Ubuntu
19.04 (and rolling forward).

On my Xubuntu machines, I have a keyboard shortcut to bring up the
keyboard shortcuts app, but when I tried that it didn't work for the
GNOME desktop.

The app appears to be /usr/lib/gnome-settings-daemon/gsd-keyboard, but
it doesn't run directly from the command line.

How would I do this?

Thanks.
