Description

Handle the keyUp message if you want to do something special when the user releases any key (or a particular key you check for in the handler).

The message is sent to the active (focused) control, or to the current card if no control is focused.

If the key pressed is the Return, Tab, Backspace, Delete, or Enter key, an arrow key, or a function key, no keyUp message is sent.

*Cross-platform note:* On Mac OS systems, the keyUp message is sent after any keyDown handlers finish executing, whether or not the key has been released. On Unix and Windows systems, the keyUp message is sent when the key is released, after the typed character has been added to the current field. To test whether a key is actually being pressed, use the keysDown function.
