Instant List
Instant list is displayed on the Dial tab to help you to use the information stored in your Contacts list and Call logs without needing to open and search those applications first. Once you enter three or more numbers you want to dial, Instant list displays entries from your Contacts list or Call logs that match the sequence that you entered.
Sequence matches
The device searches for the entered sequence anywhere in the number,
beginning, end, or anywhere in-between. The matching number sequence
is displayed within the number in blue text. The name and type of
number (i.e., Mobile, Work, etc.) associated with the number you enter
is displayed above the dialpad. When there are multiple matches, the
Instant list displays the number of matches in your Contacts list.
Tap the dropdown icon 
to view the entire list of matching entries.
