Writing Modes

Modes are used to customise individual buffers so that the text it contains can be edited in a special way. Each buffer has a single Major mode, tailoring the buffer to the type of file contained in it (i.e. C source code uses c-mode). See section Editing Modes.

Minor modes provide individual features which may be enabled and disabled individually, each buffer may have any number of minor modes enabled at once. See section Minor Modes.
