Lisp hackers who use Gnu EMACS might want to try this useful customization. It emulates the standard keybinding of CCA EMACS that makes C-Z (i.e. control-Z) a prefix which both CONTROL- and META-izes to the following keystroke. This is particularly useful for Lisp because most of the special Lisp editing commands are bound to ESC CONTROL characters. This text can be placed in the personal .emacs file in your home directory. The suspend-emacs function previously run by C-Z is still available as either C-X C-Z or C-Z C-Z . But first: The two "^Z" strings in the text below have been sanitized to pass through mailers and, as mailed, contain a two character sequence representing CONTROL-Z to humans. You will have to edit them to contain the single literal character C-Z, which can be typed in EMACS via the two-keystroke sequence: C-Q C-Z . ====================================== (defun c-m-prefix () "Apply both META and CONTROL to the next command character" (interactive) (command-execute (lookup-key esc-map (char-to-string (logand 31 (read-char)))))) (define-key global-map "^Z" 'c-m-prefix) (define-key esc-map "^Z" 'suspend-emacs)
