controlKey

controlKey posInteger

The controlKey command has no built-in effect. HyperCard sends the controlKey command to the current card when a combination of the Control key and another key is pressed.

You can handle the controlKey message as follows:

on controlKey theKeyNumber

  statements

end controlKey

HyperCard passes the following numbers for each control key combination:

Examples

 -- same as holding down Control + left arrow; no built in effect:

controlKey 28

on controlKey whichKey

  if whichKey is 28 then go previous marked card

  else if whichKey is 29 then go next marked card

  else pass controlKey

end controlKey
