If you want to add Liquid Common Lisp functions such as cd , pwd , and quit , you must import symbols individually, as the system was designed with intentional conflicts between the LCL and CLIM-LISP / CLIM-SYS packages.
Note that in Liquid Lisp, CONTROL-G and CONTROL-g both refer to the character you get by typing G with both the CONTROL and SHIFT keys held down. If you are writing a keyboard accelerator (a brief combination of keystrokes that invokes a command) and want it to refer to the character obtained by typing CONTROL and unshifted g , then refer to the character in your code as #\control-\g . If you don't, the Liquid Lisp reader will uppercase the g .
