commandKeyDown

commandKeyDown char

The commandKeyDown command provides a way of sending a Command-key event from a handler. It acts exactly as if you had pressed Command at the same time as the specified character.

HyperCard sends the commandKeyDown command to a field (if the insertion point is set) or to the current card when the user presses a Command-key combination. The value passed to the parameter variable char corresponds to the key pressed.

You can handle the commandKeyDown message as follows:

on commandKeyDown theKey
   statements
end commandKeyDown

Note: commandKeyDown is not sent for characters typed using the type command.
