Motorola

I am praying someone knows how to disable or change the smart key on this phone.

I reach in my pocket, hit a key as I'm pulling it out so I can check the time, but it changes it off of Vibrate to Loud or something where my phone rings. It's annoying.

If there is a way to set it to "Manner mode" or "Always vibrate no matter what buttons I press" that would be perfectly acceptable as well.

Any ideas?
Thanks!
