Searching contacts using keystrokes

[Tony]

Hi,

What I am looking to do is be able to copy a number from an application, and
then run a little script that will search my contacts list and return any
matching result on the phone number.

Is there a way I can open contacts using a keystroke (e.g. ctrl+shift+F does
an advanced find), and then search through all my contacts for the number I
have copied?

TIA

Tony
