GNOME settings? how do I change them?

[SwirlingVenom]

Im not sure if it is Nautilus I am supposed to access or what. But I want to know how I go about things on GNOME like changing what appears int he applications menu on the taskpane/panel how to choose what fonts are availible and add things to the apps menu. So pretty much how to access the system config and such in GNOME. Mostly what I am concerned about is accessing something that will let me changed the apps menu and add stuff to it. Thank you in advance.

**I do not know what nautilis is**

nautilus = gnome filemanager

Change fonts can be done by visiting "settings://" or something like that in nautilus. Or at the menuline, usually second or third button from the top-left corner.

menu editing currently require manual usage of "install-desktop-file" as root from a terminal.
