11.13.1 Lisp mode

Some aspects of the LispWorks editor behave differently depending on which "mode" the buffer is using (see the Editor User Guide for details). These include syntax coloring and parenthesis matching, both of which operate only in Lisp mode. Also, certain commands such as those for indentation operate specially in Lisp mode.

To make a new buffer suitable for Lisp code, you can use the New Buffer command or the File > New menu item, both of which start the buffer in Lisp mode.

If your Lisp source files are saved with an extension .lisp or .lsp , then the editor will automatically open them in a Lisp mode buffer.
