pkg_info -Q str
It allows searching for packages with substring str in their name. Very useful when you want to see, which additional packages are available for a thing, for examlpe: pkg_info -Q xfce _Auto
and then add a header like <stdauto.h> which does #define auto _Auto
like they did with _Bool in C99?
