How do you do a gift receipt at Wal Mart? Wal Mart cashiers please?

Hey everyone so I started working at wal mart a while ago and I can't for the life of me remember how to do a gift receipt on the cash register like do i hit gift receipt and then scan that item or what, also how to do like phone cards and things.I just need like a refresher course. If someone who works there or has worked there could let me know i would really appreciate the help. Thanks!
