Lock messages has the same effect as set lockMessages to true: it prevents HyperCard from sending open, close suspend, and resume system messages along the message-passing path.

Lock recent has the same effect as set lockRecent to true: it prevents HyperCard from keeping a visual record of cards visited by the user (or a handler) in the Recent Card dialog box.

Lock screen has the same effect as setting the property lockScreen to true: it prevents HyperCard from updating the screen.

Lock error dialogs prevents error dialog boxes from appearing; instead, the message errorDialog errorMessage is sent to the current card.

Locking is automatically unlocked at idle time.
