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.
