Skippy is what is best described as a full-screen task-switcher for X11. It tries to provide an alternative when taskbars or regular task-switchers aren't the most efficient way of switching tasks (like when you have a lot of applications open). When activated (currently only through a hotkey), it will arrange and scale snapshots of all windows on the current desktop and it'll let you pick a window using a mouse or a keyboard. It is pretty similar to a tool made by Apple, called Expose - http://www.apple.com/macosx/features/expose/ Skippy depends on a NetWM compliant window-manager.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
