The parameter "keyName" is the actual character of the pressed key.
The commandKeyDown message is sent to the active (focused) control, or to the current card if no control is focused.
If the Command key is pressed along with the Return, Tab, Backspace, Delete, or Enter key, with an arrow key, or with a function key, no commandKeyDown message is sent. Instead, the returnKey, tabKey, backspaceKey, deleteKey, enterKey, arrowKey or functionKey message is sent.
On Mac OS systems, the commandKeyDown message is sent when the user presses a key while holding down the Command key. On Unix or Windows systems, the commandKeyDown message]is sent when the user presses the Control key, whether or not another key is pressed at the same time.
on commandKeyDown theKey -- make Command-5 go back if theKey is "5" then go recent card else pass commandKeyDown end commandKeyDown
on commandKeyDown theKey switch theKey case "s" saveAll break case "f" findText break end switch pass commandKeyDown end commandKeyDown
Use the commandKeyDown Message handler if you want to provide Command-key or Control-key shortcuts (other than those provided in menus and button accelerators).
Remember to Pass otherwise other combinations will be not available (as Ctrl+A to select all text).
To trap a combination such as Command-Return or Control-Return, use a returnKey handler and check the commandKey function inside the handler.
