• Set the value of a key. Fails if the key doesn't exist or the value is out of range:
  gsettings set {{org.example.schema}} {{example-key}} {{value}}
• Print the value of a key or the schema-provided default if the key has not been set in dconf:
  gsettings get {{org.example.schema}} {{example-key}}
• Unset a key, so that its schema default value will be used:
  gsettings reset {{org.example.schema}} {{example-key}}
• Display all (non-relocatable) schemas, keys, and values:
  gsettings list-recursively
• Display all keys and values (default if not set) from one schema:
  gsettings list-recursively {{org.example.schema}}
• Display schema-allowed values for a key (helpful with enum keys):
  gsettings range {{org.example.schema}} {{example-key}}
• Display the human-readable description of a key:
  gsettings describe {{org.example.schema}} {{example-key}}
