The Magic of Ctrl+Shift+T: Why This Will Always Be My Favorite Keyboard Shortcut
When I discovered this simple way to reopen a browser tab, I was so delighted.

Have you ever clicked the little «X» on a Chrome browser tab when you didn’t mean to? Of course you have! I do it on a daily basis. Maybe even an hourly basis. Could it be that I’m a little too click-happy in this multitasking world? Maybe. 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 my favorite keyboard shortcut, Ctrl+Shift+T (or Cmd+Shift+T for Mac users),has my back.
I love keyboard shortcuts in general. These handy little combinations of keys may improve your productivity at work, sure, but the real benefit is the preservation of your equanimity. And Ctrl+Shift+T in particular is, I’d argue, 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 that 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, a secret power hiding in your mouse scroll wheel, 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.

Apple, I’m (Sky) Blue About Your iPhone 17 Air Color
Commentary: The rumored new hue of the iPhone 17 Air is more sky blah than sky blue.

I can’t help but feel blue about the latest rumor that Apple’s forthcoming iPhone 17 Air will take flight in a subtle, light-hued color called sky blue.
Sky blue isn’t a new color for Apple. It’s the featured shade of the current M4 MacBook Air, a shimmer of cerulean so subtle as to almost be missed. It’s silver left too close to an aquarium; silver that secretly likes to think it’s blue but doesn’t want everyone else to notice.
Do Apple employees get to go outside and see a real blue sky? It’s actually vivid, you can check for yourself. Perhaps the muted sky blue color reflects a Bay Area late winter/early spring frequent layer of clouds like we typically see here in Seattle.
«Who cares?» you might find yourself saying. «Everyone gets a case anyway.» I hear you and everyone else who’s told me that. But design-focused Apple is as obsessive about colors as they are about making their devices thinner. And I wonder if their heads are in the clouds about which hues adorn their pro products.
Making the case for a caseless color iPhone
I’m more invested in this conversation than most — I’m one of those freaks who doesn’t wrap my phone in a case. I find cases bulky and superfluous, and I like to be able to see Apple’s design work. Also, true story, I’ve broken my iPhone screen only twice: First when it was in a «bumper» that Apple sent free in response to the iPhone 4 you’re-holding-it-wrong Antennagate fiasco, and second when trying to take long exposure starry night photos using what I didn’t realize was a broken tripod mount. My one-week-old iPhone 13 Pro slipped sideways and landed screen-first on a pointy rock. A case wouldn’t have saved it.
My current model is an iPhone 16 Pro in black titanium — which I know seems like avoiding color entirely — but previously I’ve gone for colors like blue titanium and deep purple. I wanted to like deep purple the most but it came across as, in the words of Patrick Holland in his iPhone 14 Pro review, «a drab shade of gray or like Grimace purple,» depending on the light.
Pros can be bold, too
Maybe the issue is too many soft blues. Since the iPhone Pro age began with the iPhone 11 Pro, we’ve seen variations like blue titanium (iPhone 15 Pro), sierra blue (iPhone 13 Pro) and pacific blue (iPhone 12 Pro).
Pacific blue is the boldest of the bunch, if by bold you mean dark enough to discern from silver, but it’s also close enough to that year’s graphite color that seeing blue depends on the surrounding lighting. By comparison, the blue (just «blue») color of the iPhone 12 was unmistakably bright blue.
In fact, the non-Pro lines have embraced vibrant colors. It’s as if Apple is equating «pro» with «sophisticated,» as in «A real pro would never brandish something this garish.» I see this in the camera world all the time: If it’s not all-black, it’s not a «serious» camera.
And yet I know lots of pros who are not sophisticated — proudly so. People choose colors to express themselves, so forcing that idea of professionalism through color feels needlessly restrictive. A bright pink iPhone 16 might make you smile every time you pick it up but then frown because it doesn’t have a telephoto camera.
Color is also important because it can sway a purchase decision. «I would buy a sky blue iPhone yesterday,» my colleague Gael Cooper texted after the first rumor popped online. When each new generation of iPhones arrive, less technically different than the one before, a color you fall in love with can push you into trading in your perfectly-capable model for a new one.
And lest you think Apple should just stick with black and white for its professional phones: Do you mean black, jet black, space black, midnight black, black titanium, graphite or space gray? At least the lighter end of the spectrum has stuck to just white, white titanium and silver over the years.
Apple never got ahead by being beige
I’m sure Apple has reams of studies and customer feedback that support which colors make it to production each year. Like I said, Apple’s designers are obsessive (in a good way). And I must remind myself that a sky blue iPhone 17 Air is a rumored color on a rumored product so all the usual caveats apply.
But we’re talking about Apple here. The scrappy startup that spent more than any other company on business cards at the time because each one included the old six-color Apple logo. The company that not only shaped the first iMac like a tipped-over gumdrop, that not only made the case partially see-through but then made that cover brilliant Bondi blue.
Embrace the iPhone colors, Apple.
If that makes you nervous, don’t worry: Most people will put a case on it anyway.

Astronomers Say There’s an Increased Possibility of Life on This Distant Planet
Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.
The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea.
According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»
The findings were published this week in the Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. In the abstract for the paper, the team says, «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»
Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.
Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»
K2-18b is 124 light-years away and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases the chances that there are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms. The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.
More research to do on finding life on K2-18b
The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.
«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»
Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»
The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»
As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.
«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»
