How do I list absolutely every keyboard shortcut that Ubuntu/Gnome is using?

Question

Sometimes there are shortcut key that I cannot see in settings (e.g., emoji key, or app overview, normally bound to ). So I've been looking for a way to list all shortcut keys. gsettings seems to have most, but e.g. dash-to-panel only uses dconf. I'm posting my own answer below, but perhaps somebody knows a more comprehensive answer?

Answer 1

For gsettings this works too:

gsettings list-schemas | while read schema; do gsettings list-recursively $schema; done;

Lol, scratch that, this works identical by omitting the schema name ;-)

gsettings list-recursively

For completion, key bindings are often grouped by the word keybindings in the gsettings name, so you could grep by this:

gsettings list-recursively | grep keybindings

The keen eye will find that some settings might not have this word in their name (eg. org.gnome.desktop.wm.preferences mouse-button-modifier) so you could grep by < as well to find all assigned keybindings (unassigned keybindings will not show up).

gsettings list-recursively | grep '<'

I'm sure there is some clever grep regex that can match both..

Answer 2

This perl script lists all settings that gsettings and dconf knows about.

#!/usr/bin/perl
@s = split /\n/, `gsettings list-schemas`;
print "gsettings";
foreach (@s) {
    system "gsettings list-recursively $_";    
};
print "dconf";
print `dconf dump /`;
