How do I send Ctrl+Alt+Delete so I can unlock a pc?
From an Eggplant script it can be done like this:
TypeText ControlDown, WindowsAltDown, DeleteKey, WindowsAltUp, ControlUp
Always be careful when working with the modifier keys (control, shift, option, etc.) to pair each “down” with a matching “up”. Otherwise the key is left down, which tends to cause some strange behavior later in your script.
