36.1 Setting Up Abbrev Mode
Abbrev mode is a minor mode controlled by the value of the variable
abbrev-mode.
- Variable: abbrev-mode
- A non-
nil value of this variable turns on the automatic expansion
of abbrevs when their abbreviations are inserted into a buffer.
If the value is nil, abbrevs may be defined, but they are not
expanded automatically.
This variable automatically becomes buffer-local when set in any fashion.
- Variable: default-abbrev-mode
- This is the value of
abbrev-mode for buffers that do not override it.
This is the same as (default-value 'abbrev-mode).
