Get Acquainted With These Mac Keyboard Shortcuts. You Won’t Regret It

If you want to make your life easier, you should memorize these underrated Command keyboard shortcuts on MacOS.

Every time you’re on your Mac, you’re using modifier keys on your keyboard. These modifier keys, like Command and Option, are probably the most important keys you have, because they can perform shortcuts that are necessary to be more productive and efficient on your computer.

The most basic and common examples are copy (Command-C) and paste (Command-V), but these keyboard shortcuts also allow you to do more complicated things like force-close an app (Option-Command-Esc) or quickly take a screenshot (Command-Shift-4).

And the most important modifier key of them all? Command.

With it, you can copy and paste text, undo typing, select all your items at once, open a new window and so on. And in addition to all the routine shortcuts it’s known for, the Command key is much more powerful than you might think.

Even if you’re a MacOS power user, you may not be acquainted with everything the Command key has to offer, such as the ability to quickly hide windows cluttering up your desktop or search for anything stored on your computer.

Check out six not so commonly known keyboard shortcuts that use the Command key below.

1. Cycle through all the open windows on your desktop

The keyboard shortcut Command-Tab allows you to quickly step through every app window open on your desktop. As long as the window is open on your desktop and not minimized in your dock, holding down the Command-Tab combination will bring up a window with all your open apps. Continue holding down Command as you tap the Tab key to cycle through the apps and let go when the app you want brought to the front is highlighted.

2. Hide the window that’s currently open on your desktop

Instead of minimizing your window with the yellow minus button up in the top left corner, you can quickly hide any window that’s open on your desktop with the Command-H shortcut. Unlike minimizing, the hide keyboard shortcut hides the window from both your desktop and dock, without closing it completely. To open the window back up, simply click the app icon in either your dock or elsewhere. And if you want to hide all app windows except for the one in front, you can use Option-Command-H.

3. Bring up Spotlight to search for files and apps on your computer

Spotlight search is one of the Mac’s most powerful features. Bring up the search bar and type whatever you want to search for, such as text messages, emails, documents, applications, notes, music, settings, movies or locations. You can use the magnifying glass in the menu bar to bring up Spotlight search, but this keyboard shortcut is at your fingertips: Command-spacebar.

4. Highlight the URL in your web browser to quickly share it

Usually, if you’re sharing a web address you double-click in the search bar and then copy the selected text to your clipboard. However, there’s a faster way to do this: use Command-L. This will immediately highlight whatever is in the address bar in Safari, Chrome or another web browser, whether it’s something you typed or the URL of the website you’re on. You can then hit Command-C to copy it so you can paste it elsewhere.

5. Reopen any closed tabs in the Safari web browser

You may be familiar with Command-T in Safari, which opens a new tab, but there’s also a shortcut that can reopen an accidentally closed tab. Simply hit Command-Shift-T and you’ll recover whatever tab you most recently closed. And if you’ve closed several tabs and want to recover all of them, you can continue pressing the Command-Shift-T shortcut to open multiple closed tabs.

6. Open something new in various native Apple applications

The Command-N keyboard shortcut is not nearly used enough. While it’s almost universally known for opening up a new window in many popular applications, on your Mac the Command-N shortcut can open a new email in Mail, a text message in iMessage, a window in Safari, a note in Notes, an event in Calendar and more. Try it out in your favorite apps and see what Command-N can open for you.

Here’s an Image of the Asteroid Everyone Was Worried About

NASA’s James Webb Space Telescope captured a glimpse of the asteroid that had a chance of impacting Earth three months ago.

It’s not every day that an asteroid causes as much buzz as 2024 YR4. At one point, the asteroid had a 3.1% chance of hitting Earth, creating plenty of headlines about its potential impact. The threat is all but gone, but now we have pictures of the once-worrisome asteroid.

The imagery was captured by NASA’s James Webb Space Telescope and posted by the European Space Agency on Wednesday. The JWST captured the asteroid with two of its cameras, including the Near-Infrared Camera and the Mid-Infrared Instrument. The former measures reflected light, while the latter shows thermal energy.

The pictures demonstrate a couple of fun facts about the asteroid. It is the smallest object ever targeted by JWST’s instruments to date, and it’s one of the smallest objects ever directly measured. Estimates initially put the asteroid at around 40 to 90 meters. The actual size turned out to be 60 meters or around 180 feet.

«These measurements indicate that this asteroid does not share properties observed in larger asteroids,» the ESA said in its blog post. «This is likely a combination of its fast spin and lack of fine-grained sand on its surface. Further research is needed, however, this is considered consistent with a surface dominated by rocks that are roughly fist-sized or larger.»

Per NASA, the asteroid will only be visible from Earth for a little longer. The asteroid’s orbit is currently taking it away from Earth, and the agency estimates that it’ll disappear from even the strongest instruments by late April or early May. It won’t be visible again until 2028 when its orbit brings it back toward Earth.

The moon, on the other hand…

The 2024 YR4 asteroid caused quite a stir when astronomers first reported it via the Minor Planet Center in December 2024. Based on the data collected on its trajectory at that point, the asteroid had a 1.3% chance of hitting Earth.

The percentage fluctuated over the next few months, reaching as high as 3.1%. After further research, the odds dropped dramatically to 0.28%. Per NASA’s Sentry tool — which monitors asteroids that may impact Earth — the threat now sits at 0.00078%.

The moon may not be so lucky. Per NASA, the odds of the asteroid impacting the moon are somewhere around 3.8%, which is even higher odds than the asteroid ever had of impacting Earth. Scientists are gathering data before the asteroid disappears, but it’s likely we won’t know more until the asteroid comes back into view in 2028.
