Spotlight Search has been completely redesigned in Yosemite from the old Spotlight Menu function. You can still search for files, but in addition you'll get information from the Internet such as movie times, Wikipedia, maps and recommended web pages. You can also do unit and currency conversions and math. File searches can be filtered by kind and date. You can also use logical functions like OR and - (not) to get better results. Find out all you can do with Spotlight Search in Yosemite.
There are hundreds of keyboard shortcuts for Mac users. There are Mission Control shortcuts, Finder shortcuts, system shortcuts, application shortcuts and more. Many you can find by just looking through the menu bar for that application. You can find system ones by looking in the System Preferences under Keyboard.
But some keyboard shortcuts are more useful than others. And some are harder to remember than others.
So MacMost has compiled a list of our top “power user” keyboard shortcuts for Mac OS X 10.10 (Yosemite). Here they all are on a single PDF page, downloadable and printable: The MacMost Yosemite Power User Keyboard Shortcuts. Download it and pass it along!
