keyDownkeyDown char
The keyDown command simulates a key press from within a handler. It acts exactly as if the user pressed a character from the keyboard. HyperCard sends the keyDown command to a field (if the insertion point is set) or to the current card when the user presses a key. The value passed to the parameter variable char corresponds to the key pressed. You can handle the keyDown message as follows: on keyDown theKey statements end keyDown
Note: keyDown is not sent for characters typed using the type command. Demo Scripton keyDownDemo -- The keyDown messages are handled in the script of this card show bkgnd field "demo field" put "Type any key..." into bkgnd field "demo field" put "Press the Return key to continue..." into ¬ line 6 of bkgnd field "demo field" end keyDownDemo
