Dial by name...

Hi all. kinda new to the BB thing and I'm stumped. One of my clients called me and left me a voicemail...I called back the companies main number and when the auto-attendant picked up it said to dial the first four letters of the persons last name.....umm how do I do that? The full keyboard doesnt work in phone mode. Is there a button I can press that'll activate it so that I can dial by name?

Hold down the ALT button and hit the letters you need.

I was puzzled myself... that's why he's a genius!!!
