Default [Q] Changing Button activities of Xperia mini ICS .587

How can I change my Xperia mini (ICS. 587) menu key to small app key?

I have changed "MENU" in "system/usr/keylayout/cyttsp_key.kl" to "APP_SWITCH" but it made my menu key to recent app key but what I tried is to make menu key to small apps key.

So anyone can help me to change my menu key to small apps key and long press home button in to recent apps?
