Keyboard shortcuts are a common aspect of most modern operating systems and associated software applications. Their use is pervasive enough that some users consider them an important element of their routine interactions with a computer. Whether used as a matter of personal preference or for adaptive technology, the pervasiveness of common conventions enables the comparison of keyboard shortcuts across different system comparisons in widely used operating systems. In Mac OS x these are the basic and important shortcut keys.
- Command + R— Recovery Mode
- Command + Up Arrow— Immediately scroll to the top of any webpage.
- Command + Down Arrow— Immediately scroll to the bottom of any webpage.
- Command + Semicolon— Cycle through misspelled words in any given document.
- Command + 1 (2, 3) — Use this shortcut to conveniently cycle through any open tabs you have in your browser. Command + 1 will take you to the first tab, Command + 2 will take you to the second, and so on.
- Option + Delete— This handy keyboard shortcut will delete words one word at a time, as opposed to one letter at a time. This works all across OS X, whether you’re typing in TextEdit or even when typing a website into your browser’s URL bar.
- Command + H— Quickly hide all open windows from the currently active app.
- Command + Shift + T— Instantly open up the most recently closed tab in your browser. This is a lifesaver if you accidentally close a window and can’t remember the URL.
- Command + F3— This handy shortcut instantly removes all app windows from view and lets you take a gander at your desktop. To bring your apps back, simply press the keys again.
- Option + Shift + Volume Up/Volume down— Increase or decrease your machine’s volume in much smaller increments. This comes in especially handy when you’re trying to get your audio output levels just right
