The IDE preference options are now all shown in a single Preferences window which is easier to use than the separate global and per-tool preference dialogs seen in LispWorks 5.1.
Raise the Preferences window by
Tools > Preferences...
. On Cocoa, press
(comma) or select
LispWorks > Preferences...
The Preference options you choose affect all tools including those currently on screen, as well as those created later and after restarting LispWorks.
