an easy way to search contacts on mig33 contact list

hi friends i know that some people have too many contacts on mig33 and it's a bit difficult for them to search their contacts on mig33 contact lists.not too difficult but it takes time.i have an easy way to search contacts but maybe some of you know that but for those who don't know.for example you have 50 contacts and you reached your 35th contact while searching and want to scroll "go" back to the top at once how will you go?i tell you,just press 1 from your phone keypad and you will be at the top on Chat Rooms just like this if you press 7 from your keypad you'll be at the bottom and if you wanna search one of your contacts quickly.press " 9 " and it'll jump over 7 or 8 ID's and use " 3 " too to go back by jumping over your contacts
