I upgraded from Lion to ML before I thought about creating a key. Does the is leave the installation file on the ssd afterthe install or is it automatically deleted? If possible can someone please direct me to a step by step guide on how to proceed and what software to use? Thanks.

It gets deleted after you do the install. Just redownload from the App Store and use this free app to make your USB key.

Much thanks! If I create the USB key from my Air, will I be able to use the key on both the Air and my iMac or do I need a separate key just for iMac?

Or you can use disk utility to make your usb key. Just follow these easy 4 steps in the pic. Is how I make mine. You can use the key on both.
