From the developer:
Mac OS X blocks the ability of third-party programs to use the Command-Tab (Apple-Tab) keystroke as a hotkey. PullTab allows you to reclaim the Command-Tab and Command-Shift-Tab keystrokes from the Mac OS X Dock. The reclaimed keystrokes can then be used in other applications, including third-party application switchers.
