impaired vision, but it's also a quick, albeit low-fi way of zooming into pictures
or videos if you don't want to use the application's own zoom tools. Note that

method. Instead, you simply make the pixels larger.
Using a More Accurate Zoom
By default the zoomed image is antialiased; that is, the rough edges of pixels
are smoothed over, giving a slightly blurry effect. To quickly switch off
antialiasing while zooming, which can give you a less blurred zoomed image,
hit OPTION + COMMAND +. Hit the same key combination again to reactivate

There's a couple of cool ways to quickly rename files, as follows:

hit ESC . If you want to rename the entire file including its file extension,
simply hit COMMAND + A to select the entire filename after hitting RETURN .
• You can rename a file as you're editing it, although only in compatible
apps (which include most of OS X's built-in apps). To do so, click the
filename in the title bar, and then select Rename from the menu that
appears. Then type the new filename in the highlighted text field.
