The lack of documentation is regrettable, but I haven't had much trouble
lately making it do anything I've tried.  (Admittedly, I haven't tried
everything possible.  In particular, I haven't tried to start a wireless
connection at boot, which seems to be the most common problem scenario.)

Right-click the applet and uncheck Enable Networking or Enable Wireless,
as appropriate.

All my wireless connections are editable from the applet.  The wired
connections are editable from s-c-network, as mentioned above.
Apparently Fedora devs think that that's the way to go.

See s-c-network.  It might be nice if nm-applet started s-c-network when
you tried to edit a "non-editable" connection, but if this is where an
"ordinary user" would think to
edit /etc/sysconfig/network-scripts/ifcfg-eth0, then s-c-network the way
to do it.

See s-c-network.

BTW, I have a desktop with a recent F10 install, fully up to date.  It
has only a wired interface.  That interface comes up at boot (before
login) with no problem using NM, not using the network service.  I have
not made any changes to its /etc/sysconfig/network-scripts/ifcfg-eth0.
s-c-network shows that it is on at startup and controlled by NM.

Means "Never connected to that interface."  Apparently incorrect or
meaningless for System eth0, but seems to work for wireless.
