To make things quicker, you can sometimes get away with not putting in the TLD for a domain name. This doesn’t work all the time (depending on the popularity of the website), but it gets it right most of the time.
You have to have Google set as the default search engine for this to work. After this is set, you can just put "apple" into the browser, and press "Go". It’ll automatically take you to the Apple.com website.
