1) You don't need to hit enter, it looks up the domain as you type. Pressing enter to be redirected to GoDaddy is a convenience. There's a bunch of other useful shortcuts too, like Ctrl + S.

2) I have no idea why you think looking up a domain on GoDaddy will cause the price to go up, or someone to buy it out from under you, or whatever else you've dreamt up. Must be leftover paranoia from the Moniker fiasco a couple years ago?

Either way, I'm done with this conversation.
