Working with the key down and key up events via event taps requires the user to turn on the "Enable access for assistive devices" setting in the Universal Access pane of System Preferences. Traditionally, apps that require this setting to be turned on test whether it is on and, if not, ask the user to turn it on (often opening the Universal Access pane for the user on request). Starting with Tiger, you can turn this setting on programmatically by embedding an AppleScript script in your application, but it requires the user to authenticate and leave the setting turned on globally. Starting with Leopard, you can make a single application "trusted" by accessibility, by authenticating once at install time or first launch without turning on the global setting at all (this feature was implemented in Tiger but is said to have been rendered useless by a bug; I haven't tried it in Tiger, but I suspect it might actually have worked if done right). However, I'm not sure event taps will notice the special function keys on any keyboard. The OP could do some initial testing of this with my free PreFab Event Taps Testbench application, here: <http://prefabsoftware.com/eventtapstestbench/>. -- Bill Cheeseman - [EMAIL PROTECTED] Quechee Software, Quechee, Vermont, USA www.quecheesoftware.com PreFab Software - www.prefabsoftware.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
