When you're in a hurry, it can be a real nuisance trying to type out an entire website address into your phone. Particularly if you're at the airport frantically searching for your flight details, your freestyle cooking is going wrong and you need a recipe quickly, or you're trying to beat your friend to the latest sports results. There simply isn't time to waste, and the iOS developers clearly feel you on this one.
When you're typing out a web address, you can save a bunch of time by making use of this keyboard shortcut. Simply hold the period icon when you've typed out the address to reveal a menu of URL suffixes. You'll see the usual suspects, such as .com and .co.uk, as well as the more obscure, including .edu, .ie, .net, and .biz.
