functionKeyfunctionKey posInteger
Note: posInteger must yield a number between 1 and 15. HyperCard sends the functionKey command to the current card when the user presses one of the function keys on the Apple Extended Keyboard. The functionKey command performs an undo, cut, copy, or paste for the values 1 through 4. Integer values 5 through 15 have no built-in effect. You can handle the functionKey message as follows: on functionKey whichKey statements end functionKey
ExamplesfunctionKey 1 -- performs undo functionKey 2 -- performs cut functionKey 3 -- performs copy functionKey 4 -- performs paste -- An example handler: on functionKey whichKey if whichKey is 5 then myCoolHandler else if whichKey is 6 then choose browse tool else if whichKey is 7 then choose button tool else if whichKey is 8 then choose field tool else pass functionKey end functionKey
