Hello Community !

I am currently programming a small app with WRT. So far everything works great.
Now I would like to program that my application does not allow screen saver, or the KeyLock starts.

Here is my question:
How can I in WRT disable the screensaver, or disable the KeyLock ?
OR:
Is there a way in WRT to simulate a "key-press-event", that don't start the screensaver ?

Thanks for answers ! (Sorry for my bad english)
