Activating a hotkey no matter what application is active

[Sean Farrow]

Hi: 
is there a way to activate a window-eyes hotkey (speech or braille) no
matter what set file is active/what set key the hotkey is defined in.
for example read to end.
Does the activation of a hotkey insert keys in to the keyboard input
stream, or does it just activate the hotkey internally within the
window-eyes process?
Any help apreciated.
Sean.
