Some applications have the Qt<>DCOP Bridge enabled, i.e. an interface to call 
slots of Qt objects through DCOP

You can get a list by calling the function "objects" of interface "qt" on the 
commandline or in KDCOP, for example

dcop konqueror-somePID qt objects

and search there, e.g. using grep

"up" for example would be

dcop konqueror-PID qt/KXMLGUIClient-KActionCollection/up activate

I think there is an X11 application that can generate X11 events for a 
specified target window
