Problem of home button action after changing keymap

[alteclansings]

Hello,
My Droid A855 has a screen problem (partially won't work) and I decided to change the keymap.
I changed the Right Atl key for "Back" first.This worked great.and then I also changed the Right Shift key for "Home"
then it didn't act as home buton... It goes back to lock screen. and it made the search key disable for some reason.
What I did is changed "key 54 SHIFT_RIGHT WAKE" portion to "key 54 HOME WAKE" and "key 54 HOME WAKE_DROPPED"
both didn't work.
To make it act as home button, anyone know how to write on .kl file?

Thank you
