+Since StumpWM is a Lisp program, there is a way for youto evaluate
+Lisp code directly, on the same Lisp process that StumpWM is running on.
+Type @kbd{C-t :} and an input box will appear. Then type some Lisp
+expression.
+
+When you call eval this way, you will be in the COMMON-LISP-USER
+package. In order to use all the functions and variables defined in
+the StumpWM manual, you need to explicitly mention the package stumpwm:
+
address@hidden @asis
address@hidden stumpwm:*mode-line-border-width*
+Reads the value of *mode-line-border-width*.
+
address@hidden (setf stumpwm:*mode-line-border-width* 3)
+Sets the variable *mode-line-border-width* to 3.
+
address@hidden (stumpwm:set-prefix-key (stumpwm:kbd "C-M-H-s-z"))
+Calls the set-prefix-key function (and sets a new keyboard prefix)
