Program to switch off phone when keyboard is closed
 

Is there a program that will turn off the phone when you close the keyboard?

I use my TP only in landscape mode. my job gives me a boat load of texts that I just quickly reply to then continue with my work.

Once I get the text, I just pull it out of the holster, slide open the keyboard his messaging, read, reply and slide the keyboard back and back into the holster it goes.

I know it's just a extra button. But when you're replying to 200-300 texts a day it's 200-300 button presses that could be avoided.

Any help would be grateful!
