enterInField

HyperCard sends the enterInField command to a field when the user presses Enter and the insertion point is in the field. This command saves the results of any changes the user or a handler makes to a field and closes the field.

HyperCard sends a closeField message if the user made changes to the text or sends exitField if the user did not make any changes).

You can handle the enterInField message as follows:

on enterInField
   statements
end enterInField
