Biblical Greek and Latin manuscripts had no spaces between words you just had to be familiar with where words started and stopped to read a text like this. But we should be thankful to the spacebar for more than just its capital word-separation calling because it can also serve considerably few tricks in several situations.
In any description that presents Play and Pauses instruments, you can use the spacebar to alternately play and pause the content. This includes videos and slideshows, as well as audio-only files such as those you play in Apple’s iTunes and GarageBand.
Spring-loaded papers are one of OS X’s most-overlooked timesavers. In the Finder, move an item, hangover a folder with it, and after a brief pause (so the Mac knows you’re not simply hesitating before separating the item in) a Finder window sources open, revealing the folder’s contents. This makes it easy to see that you’re moving or copying an item into the correct place if your folder names are less than revealing. It also explains getting into subfolders, because you can continue the hover-and-spring method into further folders. But you can skip the pause when you’re floating over a folder: press the spacebar for prepared springing.
Spring-loaded folders work from the Dock, too, so you don’t have to drop an item carelessly into a closed docked folder. Press the spacebar to withdraw the hover time here, too.
Even if you turn off the spring-loaded folders highlight by going to Finder -> Decisions and unchecking the Spring-loaded Folders And Windows setting, touching the spacebar still springs open a pamphlet when you hang over it continuing an item.
When you need to document some aspect of your Mac’s behavior, a screenshot of the full protection is seldom important. Sure you can press Command-Shift-4 to select an area to capture to the Desktop (Command-Shift-3 saves the full screen as a file on the Desktop), but if you add the spacebar you access more options.
Touching the spacebar before you drag across an area to apprehend it changes your cursor to a camera and lets you select a complete window or a dialog box with a click. Press the spacebar after you transported a selection rectangle but before you let it and you can move the choice the rectangle around on the screen to adjust its position before caught the shot go off the spacebar with the mouse button still down if you want to adjust the size of the rectangle after you move it.
