jed supports two internal modes as well as user defined modes. The two internal modes consist of a ``C'' mode for C Language programming and a ``Wrap'' mode for ordinary text editing. Examples of user defined modes are Fortran mode and DCL mode.
Online documentation is provided for nearly every mode jed defines.
For help on the current mode, press ESC X and enter
describe_mode. A window will appear with a short description of the
special features of the mode as well as a description of the variables
affecting the mode.
