Unlock screen lets HyperCard update the screen after a lock screen command. (Click the placeholders effect, speed, and image to see their possible replacements.) Optionally, you can add a single visual effect. You can lock the screen, perform
actions on the card, and then unlock the screen with a visual effect.
Unlock messages lets open, close, suspend, and resume messages traverse the message-passing path. Unlock recent lets HyperCard keep a visual record of visited cards in the Recent Cards dialog box. Unlock error dialogs lets HyperCard show error dialog boxes when an error occurs. Examples
