simulate keystroke

[Terry Judd]

Hi Larry - it might not be the ideal way to do it but it seems to work quite
reliably here. All I have are two buttons on a stack with an empty button
named 'cancel' that has its autohilite set to false and a button named 'run'
that has the following script - slightly modified from the previous version
so that you get some feedback in the message box.

ON mouseUp
   REPEAT forever
      wait 0 milliseconds
      put the milliseconds
      IF within(btn "cancel",the mouseLoc) THEN
         put "cancel"&& the milliseconds
         IF the mouse is down THEN
            set the hilited of btn "cancel" to true
            wait until the mouse is up
            set the hilited of btn "cancel" to false
            exit repeat
         END IF
      END IF
   END repeat
END mouseUp
