10 Simple Customization of LispWorks

10.2 Using ! for :redo

The default way of redoing the previous command from the command history is via:redo. If you want to use! (exclamation mark) instead of:redo, add the following to your.lispworks file:

(set-macro-character #\!
   #'(lambda (stream char)
    ':redo))

You may wish during some sessions to reset! back to its normal role as a character. Type in:

(set-syntax-from-char #\@ #\!)
