dconf-editor. There is no menu, but I did discover that you can press
Ctrl+F and enter a search term.
However, I do not know what
Ctrl+F actually searches. When I enter a term (e.g.
unity-greeter), I receive no results.
I have also tried
gsettings at the command line, but with no luck whatever options I have tried; I must be doing it incorrectly.
How do I search for a specific key or value within dconf?
