Andres,

This is a pretty standard modification to the registry so don't be  
scared :-)

Here is an example that registers an app to process a url protocol.  
Note that I am setting ssurl\URL Protocol to a space. This is because  
Rev deletes registry keys if you set the key to an empty value. I'm  
not sure if that is the wisest way to go about it but that is what Rev  
does. In any case the protocol still works with the value set to space.


on mouseUp pMouseBtnNo
     put "HKEY_CLASSES_ROOT\" into thePrefix
     put setregistry(thePrefix & "myurl\", "URL:Alert Protocol") into  
wasSuccessful
     put setregistry(thePrefix & "myurl\URL Protocol", " ") into  
wasSuccessful
     put setregistry(thePrefix & "myurl\shell\open\command\", \
             quote & "C:\Program Files\ScreenSteps\ScreenSteps.exe" &  
quote && quote & "%1" & quote) into wasSuccessful
end mouseUp
