Scheme Interaction Mode Keyboard Mapping

 

When a buffer uses Scheme Interaction mode, the keymap  mred:global-scheme-interaction-mode-keymap the keymap  mred:global-scheme-mode-keymap is inserted into the chain of keymaps from the buffer's private keymap (before the global keymap). This keymap is created at system startup time and initialized by   (mred:setup-global-scheme-interaction-mode-keymap mred:global-scheme-interaction-mode-keymap).

The mred:setup-global-scheme-interaction-mode-keymap procedure chains the global Scheme mode keymap --  mred:global-scheme-mode-keymap -- to the argument keymap and installs the following functions:  

•   ``put-previous-sexp'' (key events) -- Sends the buffer copy-prev-previous-expr. This should copy a previously evaluated S-expression to the current prompt.
•   ``next-previous-sexp'' (key events) -- Sends the buffer copy-next-previous-expr. This should copy a previously evaluated S-expression to the current prompt.

and these functions are bound to these keys:

• M-p : ``put-previous-sexp''
• M-n : ``put-next-sexp''
