ScreenSaver Start

ScreenSaver Start sits up in your menu bar allowing you to quickly start your screensaver by configuring a global hotkey.

It can additionally be configured to start at login, so it's always ready when you need it.
Handy for quickly locking your screen (when your Mac is configured to lock with the screensaver) ScreenSaver Start is a useful addition to any Mac user's productivity toolkit. Useful for quickly keeping prying eyes away from sensitive information... With a quick tap on the keyboard, everything you are currently working on is quickly hidden from view.
