is used to search for a particular regexp in all the files referenced by a LispWorks
definition. Enter the regexp in the
Regexp Search String
box and the system names in the
box. Multiple system names can be entered, separated by semicolons.
Check Case sensitive to make the search match only the case of letters exactly as entered.
You can also do a System Search in a "system" defined by another source code manager such as ASDF, if you have configured LispWorks appropriately. See ASDF Integration for the details.
