### 1.1 How to Begin Using EDT

To start the EDT Emulation, first start Emacs and then enter `M-x edt-emulation-on` to begin the emulation. After initialization is complete, the following message will appear below the status line informing you that the emulation has been enabled: “Default EDT keymap active”.

You can have the EDT Emulation start up automatically, each time you initiate an Emacs session, by adding the following line to your `.emacs` file:

    (add-hook 'emacs-startup-hook 'edt-emulation-on)

Important: Be sure to read the rest of this manual. It contains very useful information on how the EDT Emulation behaves and how to customize it to your liking.

The EDT emulation consists of the following files:

- `edt.texi`—This manual.
- `edt-user.el`—An example customization file (located in the Emacs distribution etc directory).
- `edt.el`—EDT emulation functions and default configuration.
- `edt-lk201.el`—Built-in support for DEC LK-201 keyboards.
- `edt-vt100.el`—Built-in support for DEC VT-100 (and above) terminals.
- `edt-pc.el`—Built-in support for PC 101 Keyboards under MS-DOS.
- `edt-mapper.el`—Create an EDT LK-201 map file for keyboards without built-in support.
