Privacy Keys Pro

Tired of scrambling around to minimize or close your internet browser when someone walks in? Want more privacy while browsing the internet, checking your internet banking or chatting online? Privacy Keys Pro lets you use a "Panic Key" to instantly hide your chosen windows. It can even automatically pop up other, less sensitive programs at the same time (eg hide your online game and simultaneously ping up the Google News website, all at the press of a button).
