Skill code to generate pins and label on metal by a bindkey

Hi,

             I though of writing a code to create pins on metals just by pressing a bindkey. If a path segment is partially selected at right end then the pin should be placed on the path segment at right end with the same width and height as of pathwidth along with a label same as the name of the path segment. If the Path segment is fully selected place a pin entirely on the mental along with its label.

Is there any Ideas? and also how to access the "Route net name" of a Path Segment that we see when query path segment  is done in its connectivity tab.

Thanks.
