Find the answer
Yosemite has refined the way we find the answers to all sorts of questions, including some clever shortcuts that you probably hadn’t noticed.
1 Yosemite includes a Spanish to English dictionary. Open Preferences in the Dictionary app and tick the box next to ‘Gran Diccionario Oxford – EspañolInglés’. You can now translate any Spanish word in most OS X apps by right-clicking it and choosing ‘Look Up’.
2 If you need to do a quick sum, you can hit ç+ Space to bring up Spotlight and type it there. Or click the Notification Centre icon in the top-right corner of the screen to slide a basic calculator into view.
3 Spotlight can also search for songs. So if you don’t want to wait for iTunes to load, just hit ç+ Space, type in the name of the song and play it directly from the Spotlight window.
4 If you want search the internet without being tracked by Google (or anyone else), you can use DuckDuckGo. Safari 8 allows you to switch search engine directly. Click the magnifying glass icon in the address bar and select DuckDuckGo. 5 By default, Safari 8 will only show you the site you are browsing, rather than the URL of the specific page. If you want to revert to the old way, click ‘Show full website address’ in Safari > Preferences > Advanced.
Play individual songs straight from the Spotlight search window, without starting iTunes.
