VNC Client that can send Ctrl+Alt+Delete? Is there a VNC Client for OS X that can send Ctrl+Alt+ Delete? I've googled, searched have not found. I frequently VNC into Windows machines and need to send this key combo in order to log in.
The built-in Screen Sharing application on OS X is a VNC client that can send Ctrl-Alt-Del:

Laptop keyboard: fn+control+command+delete

Full-size keyboard: control+option+delete
