If You Use a PC, You Need to Know About Ctrl+Shift+T

This keyboard shortcut is legit.

I can’t be the only one who routinely clicks the «X» on a Chrome browser tab when I only meant to switch to it. Maybe my mouse cursor speed isn’t calibrated properly, or maybe I’m just too click-happy. But if I’m not particularly prudent about my cursor positioning, it’s because I have a secret weapon up my sleeve: I know that Ctrl+Shift+T has my back.

What is Ctrl+Shift+T (or Cmd+Shift+T for Mac users)? I’d argue that it’s one of the most important and useful keyboard shortcuts there is, right up there with Ctrl+Z. In fact, it performs a similar function: undoing a mistake. Specifically, the mistake of accidentally closing a browser tab or window. Ctrl+Shift+T is the easiest way to restore a browser tab you didn’t mean to X out.

Let’s walk through how to use it, plus all the other ways to restore lost tabs in any browser. And don’t miss our list of the best Windows 11 keyboard shortcuts, the essential Mac keyboard shortcuts, and a Google Chrome trick that organizes all your tabs for you.

Four ways to reopen closed tabs in Google Chrome

Google Chrome gives you a few options for restoring tabs and windows after you’ve closed them, and depending on your needs, it’s good to know how they all work. Note, however, that restoring closed tabs isn’t an option when browsing in incognito mode.

1. Keyboard shortcut method

The quickest way to restore a single tab you closed by accident is with a keyboard shortcut. On a PC, use Ctrl+Shift+T. On a Mac, use Cmd+Shift+T. If you want to restore multiple tabs, or if you need a tab you closed a while ago, just keep pressing Ctrl+Shift+T and your tabs will reappear in the order in which they were closed. Bonus: If you accidentally close your entire browser window altogether, just open a new Chrome window and the keyboard shortcut will reopen everything at once. This is a great trick for the times when a system update forces you to close your browser or restart your computer altogether.

2. Browser history method

Your Chrome browser history also keeps track of recently closed tabs. It’s not as lightning-fast as a keyboard shortcut, but this method is useful if you closed the tab a long time ago and need to refer back to it.

There are a few ways to access your browser history in Chrome. One way is to use another shortcut: Ctrl+H. Another is to click the hamburger menu in the top right corner of your browser, then select History. And a third option is to type «chrome://history» into your address bar, then press enter.

However you arrive at your browser history, once there you’ll have access to all the websites and tabs you’ve viewed, in reverse chronological order. Clicking on a result will reopen it for you. Going through the hamburger menu also has a built-in list of Recently Closed tabs, which you can select to reopen.

3. Tab search method

Ever noticed the little downward-pointing arrow in your Chrome tab bar? In Windows, it’s right next to the icons for minimizing, maximizing and closing your window. (On Mac it’s at the top right.) This icon is Chrome’s built-in tab search feature, which itself can be accessed with a simple keyboard shortcut: Ctrl+Shift+A. Tab search shows you a list of all the tabs you currently have open, and another list of your recently closed tabs. You can scroll through the lists to reopen or switch to the desired tab, or use the search bar to find it with a keyword. This comes in handy for those who keep dozens of tabs open at all times.

4. Taskbar method

If you’ve got a Chrome window opened — or if the app is pinned in your taskbar — right-click the icon from the taskbar and you’ll see a short list of links: Most visited and Recently closed. From there, you can restore a tab just by clicking on it. (Note these options do not appear on Mac.)

Bonus: ‘Continue where I left off’ method

There’s a Chrome setting that essentially makes Ctrl+Shift+T the default. By toggling this feature on, every time you open Chrome, the browser will automatically reopen the tabs you had open in your previous session. To turn it on, go to your Chrome settings (also through the hamburger menu), then On startup. Select the Continue where you left off option.

What about other browsers, like Firefox, Microsoft Edge and Opera?

The Ctrl+Shift+T keyboard shortcut will work in other browsers, too (as well as right-clicking the tab bar and selecting Reopen closed tab). Most of the other methods of reopening a tab work across browsers too, though the menu labels and options may differ. The experience is largely the same on a Mac, with the exception of the taskbar method.

For both Firefox and Microsoft Edge, you can also go through your browser history to find and reopen a tab you accidentally closed. Firefox has a dedicated sub-menu under History called Recently closed tabs. Microsoft Edge has a tabbed History menu for All, Recently closed and Tabs from other devices. In Opera, if you have the sidebar enabled — and if History is one of the elements you’ve elected to include in the sidebar — clicking the History icon from the sidebar will also pull up a list of recently closed tabs.

The other browsers also offer a setting to reopen the previous session’s tabs automatically upon startup. In Firefox, go to Settings > General and check the box under Startup labeled Open previous windows and tabs. In Microsoft Edge, go to Settings > Start, home, and new tabs and under When Edge starts, select open tabs from the previous session. And in Opera: Settings > On startup, then check the box for retain tabs from previous session.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
