6 Advanced Features

The editor can be customized, both interactively and programmatically, to suit the users requirements.

The chapter 3 Command Reference provides details of commands used to customize the editor for the duration of an editing session (see 3.28 Keyboard macros, 3.32 Key bindings, 3.30 Editor variables). This chapter contains information on customizing the editor on a permanent basis.

There are a number of ways in which the editor may be customized:

• The key sequences to which individual commands are bound can be changed, and key bindings can be set up for commands which are not, by default, bound to any key sequences—see 6.1 Customizing default key bindings.
• The indentation used for Lisp forms can be modified to suit the preferences of the user—see 6.2 Customizing Lisp indentation.
• Additional editor commands can be created by combining existing commands and providing specified arguments for them—see 6.3 Programming the editor.

Note that the default configuration files mentioned in this chapter were used when LispWorks was released. They are not read in when the system is run, so any modification to them will have no effect. If the user wishes to modify the behavior of LispWorks in any of these areas, the modifying code should be included in the .lispworks file, or an image containing the modifications should be saved.
