How do I clean my Blackberry keyboard?

How do I access a dial-by-name directory with my blackberry qwerty keyboard?

• When you call a company and they ask you to dial the first 3 letters of the person's last name to find their extension...the buttons you press on the blackberry smart phone qwerty keyboard don't correspond with the traditional "multitap" system (ie. #2=ABC, #3=DEF, etc.).

• Answer:

  Hold down the Alt key while typing the actual letters you want. The BB will translate to numbers you want. You can also do this while on a call.
