Can I turn my screen off another way?

[quickstang]

Is there a way to turn the screen off another way besides the top power button? For instance lets say I send a txt and want to turn off the screen right away, do I have an option to assign it to a button, or is there a tweak that I can do where I can just maybe even tap an icon on the screen?

I'm not looking to totally shut the phone off, just turn the screen off a more convenient way then the top button.

I had a Treo before, and the power button was right by the keys and screen, so you could even do a one hand deal and hit the button to turn it off.

I just thought about this option when I had my phone on my bed, sent one last text one handed with the right hand while the phone was still on the bed, but then went...this will be tricky to get to the power button to turn the screen off.

I noticed the button on the far right of the phone. Don't have my manual in front of me, so I dont know if it is an "end" button, but with a single click, it doesn't seem to do anything. I figured a registry hack could assign this button to turn the screen off with a press of it.
