Which system files configure global keyboard shortcuts?

Question

Obviously in many distros you can set global keyboard shortcuts via the GUI system settings. However, where are these stored?

I don't mean the keyboard config, but I mean keyboard shortcuts like super-a for applications or suoer-left-arrow to move windows. These cannot be set using xmodmap, but have to be set e.g. in X11 or gnome?

I'm particularly looking where ctrl-shift-e is set, but would like to understand the mechanism.or setting such global keyboard ahortcuts (that initiate "system functions" like window moves).

I'm aware that this will differ between distros, and tips about Ubuntu 19.04 / X11 are particularly welcome. However I'm interested in general.

In Ubuntu, the following perl script shows system settings, including keybindings.

#!/usr/bin/perl

@s = split /\n/, `gsettings list-schemas`;

foreach (@s) {
    system "gsettings list-recursively $_";    
};
