Contact Number Dialling

[Guest]

I didn't know this before and found out by coincedence. In the Contacts (or through pressing the green key once) you have an entry and the default number is for example mobile (m), but you want to call his work number, you can go left or right to change the number (actually only the letter changes m,w,txt,...etc) and then you can dial a different number instead of opening the entry and going down to the required number.
