KeyQuencer, QuicKeys et al operated by patching OS9 low-level routines  
to inject fake events, this is not possible under OSX in the same way  
(which is a good thing really)

the new UI scripting in 10.2 works via the accessibility APIs: it does  
not really inject events, but instead relies on the OSX widgets'  
adherence to these APIs to have them simulate that they have been  
clicked... so e.g. a non-native widget in Tk could not be scripted this  
way.

for GUI scripting docs, c.f. the following
	http://www.apple.com/applescript/GUI/
	http://www.prefab.com/uibrowser/

the OS X window server does have some support for synthetic events via  
the remote operation API, c.f.
	/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ 
Frameworks/CoreGraphics.framework/Headers/CGRemoteOperation.h
this is what e.g. AppleRemoteDesktop uses to control remote machines,  
and quite possibly QuicKeysX and such, not sure...
I don't know of any apple script interface to this, but if probably  
wouldn't be too hard to write one, or a tcl binding for that matter.

Cheers,

Daniel
