A couple of easy to remember keyboard shortcuts will dramatically boost your productivity when navigating around documents and webpages throughout OS X, giving you the ability to instantly jump to the beginning or end of a scrollable document. These are universal on all Macs and should work regardless of what keyboard you’re using.
Jump to the End of a Document with Command+Down Arrow
Jump to the Start of a Document with Command+Up Arrow
These command+arrow tricks are two particularly useful keystrokes out of a handful of text-specific navigation shortcuts to learn, if you want to see some more we’ve got you covered.
Works on Web Pages in Chrome & Safari
Even if you’re never in Pages or jumping around in text documents, you should get some use out of the two End and Start tricks because both keystrokes work in major web browsers too. Hitting Command+Up will instantly scroll to the top of any web page, and Command+Down will instantly jump to the very bottom of a web page. This works the same in Safari, Chrome, and Firefox.
If you’re a command line user, you can modify the keystroke slightly to jump to the very top or bottom of any Terminal window too with Command+Function+Up and Command+Function+Down
