Emacs Power Usage

Variables And Customization:

emacs obviously has its own variables.
for those who do not write lisp, there are two kinds
of scopes a variable may have: global or local.
variables will normally have a global value, and some of the
buffers may have a local variable of that name, hiding the global
value for that buffer.

various variables customize various options, one
way of customization is setting the values of variables.

we can set the value of a variable using the set-variable command:
`M-x set-variable VAR VALUE '

we can also use lisp code:
(set-variable VAR VALUE)
