There are more
than 180 variables that can be used to customize Org. For the
sake of compactness of the manual, I am not describing the
variables here. A structured overview of customization variables
is available with M-x org-customize. Or select
Browse Org Group from the
Org->Customization menu. Many settings can also
be activated on a per-file basis, by putting special lines into
the buffer (see In-buffer
settings).
