A button widget in the frame or dialog box to receive the CHOOSE event when a user cancels the current frame or dialog box by pressing the ESC key.
Data type: HANDLE
Access: Readable/Writeable

Any other action normally associated with the ESC key is not performed. The ESC key is any key associated with the ESC key label.

If the user presses ESCAPE in a frame that has no such cancel button and the frame is part of a frame family, the AVM applies the CHOOSE event to the first cancel button it finds within the frame family in random order.
