7 WhatsApp Web Tips and Tricks All Users Should Know



WhatsApp Web is the easy way to use WhatsApp on any computer in the world, as long as you have your phone to sign in. Once you know how to use WhatsApp Web on your PC, these tips and tricks will make WhatsApp Web even better.

Now that you know the basics of using WhatsApp Web, including what it can and can’t do, it’s time to enhance WhatsApp Web with some simple tips and tricks…

1. Learn WhatsApp Web’s Keyboard Shortcuts

keyboard shortcuts for WhatsApp Web

In order to take full advantage of using WhatsApp Web on your computer, you need to learn some keyboard shortcuts. These can make you a typing ninja who does everything a bit faster. Here’s a list of keyboard shortcuts that work in WhatsApp Web:

  • Ctrl + N: Start new chat
  • Ctrl + Shift + ]: Next chat
  • Ctrl + Shift + [: Previous chat
  • Ctrl + E: Archive chat
  • Ctrl + Shift + M: Mute chat
  • Ctrl + Backspace: Delete chat
  • Ctrl + Shift + U: Mark as unread
  • Ctrl + Shift + N: Create new group
  • Ctrl + P: Open profile status

Apart from these, you can also employ all of the universal Windows keyboard shortcuts, such as Ctrl + Shift + Equals to zoom and enlarge text. The same goes for Mac keyboard shortcuts too, of course.

2. Type and Search Emojis With a Keyboard

Instant messaging feels incomplete without emojis. But it takes forever to change from the keyboard to the mouse, click the emoji icon next to the text box, and then find the right emoji. There’s a faster WhatsApp Web trick for keyboard warriors.

While in the regular text box, type colon (Shift + ;/: Key) followed by the first two letters of the emotion you want to express. You will get a prompt of matching emojis that change with each letter you type.

:th will show this:

add emojis quickly in WhatsApp Web

:thu will show this:

type a colon followed by letters to see emoji previews in WhatsApp Web

Use the keyboard’s arrow keys to switch back and forth between the emojis displayed. Press Enter to accept.

You can also access the emojis, stickers, and GIFs button by pressing Shift+Tab when in any chat window. This will highlight the emoji icon, so press Enter to bring up the emojis, stickers, and GIFs menu. Press Tab and Shift+Tab to cycle through the three choices. Navigate within their menu with the arrow keys.

It’s a much faster way to type, and it will help if you familiarize yourself with the emoji to English dictionary.

3. Auto-Change Emoticons to Emojis (or Not)

Whatsapp Web auto-changes a set of text emoticons to emojis as a great keyboard shortcut

Some emojis don’t need the colon-and-type trick above because one of the best features of WhatsApp Web is to auto-convert them from the classic text emoticons. A helpful redditor extracted the full list of auto-converted emoticons, pictured above.

Again, learning these WhatsApp Web shortcuts for the keyboard will make your typing much faster if you practice them regularly.

That said, this auto-conversion can be annoying for some people, so there’s an easy fix to keep them as emoticons. All you need is a userscript called WhatsApp Emoticon Preserver.

  1. Install Tampermonkey, a cross-platform userscript manager, on your browser of choice.
  2. Go to WhatsApp Emoticon Preserver.
  3. Click the blue Install button.
  4. Refresh the WhatsApp Web tab in your browser.

Please note, this will show emoticon characters on your screen, but the recipient will still see them as emojis.

4. Use Multiple WhatsApp Accounts on the Same PC

How to use multiple WhatsApp Web accounts on your computer at the same time

Some people have two phones with separate WhatsApp accounts, or maybe you use a dual-SIM phone with multiple WhatsApp apps. If you want to run two WhatsApp Web accounts on your computer, you can’t just open two tabs in Chrome and sign in separately.

The best WhatsApp Web trick to use multiple accounts is to open an incognito window or different browser. So if you have one account signed into Chrome, start a new window in Incognito Mode, or fire up a second browser and go to WhatsApp Web through that. Log in as you normally would, using your other account to read the QR code.

In Incognito Mode, you can use WhatsApp Web for an hour before it automatically logs you out.

5. Read Messages Without Blue Tick Notifications

Use this WhatsApp Web trick to read messages without the blue ticks to notify the other user

As long as you have those blue tick marks enabled, people can see the exact time you read their text. You can switch off Read Receipts on your phone if you want to disable this, but there’s a cool WhatsApp Web trick to get around this.

If you are talking with someone on WhatsApp and want to read their messages without them getting a read receipt, here’s what you do:

  1. Open the chat in your WhatsApp Web window.
  2. Open a Notepad file (or any other window), and change its size so that you can see the full WhatsApp Web chat in the background.
  3. Click in the Notepad file and keep your cursor there. This is the critical step, as the computer thinks you are working in a different window.
  4. Messages will load in the background chat window, which you can see, without being marked as read with the blue ticks. Right now, they will be double grey ticks, meaning the messages are received by you, but not read.
  5. When you’re OK with marking them as read, click the WhatsApp Web chat window and those ticks will instantly turn blue.

The limitation of this method is that you can only read the content of one chat at a time. But how often do you really need to use this WhatsApp Web trick anyway?

6. Get WAToolkit Extension for Message Previews

WAToolkit is a Chrome Extension that makes up for missing WhatsApp Web features

In WAToolkit, Chrome users have an excellent extension to add extra features to WhatsApp Web. It adds two cool tricks to built-in WhatsApp Web features, including one that lets you again read conversations without triggering the Read Receipt.

  1. Background Notifications: When you get a new message in WhatsApp, you no longer need to switch to the WhatsApp Web tab to read it. The WAToolkit icon’s badge shows how many unread messages you have. Hover over the icon and you’ll be able to preview the messages, without registering them as having been read in your main chat.
  2. Full-Width Chat Bubbles: By default, WhatsApp doesn’t stretch a person’s chat bubble across the full width of the chat window. That’s why you get multi-line texts when it would easily fit in a single line of your wide desktop window. WAToolkit fixes this by changing the text bubbles to full-width.

Remember, you can also use Google Chrome extensions in Opera and other browsers.

Download: WAToolkit for Chrome (Free)

7. Enable Dark Mode for WhatsApp Web

Dark WhatsApp Web extension for Chrome enables and disables Dark Mode for WhatsApp Web in one click

Dark Mode is a hidden WhatsApp Web feature that the company hasn’t yet launched to the public. You will find articles online about how to change the code in a browser tab to enable Dark Mode, and it’s not too hard, but might seem daunting for some.

But the easier way is to download the Dark WhatsApp Web extension. It’s a neat WhatsApp Web shortcut to implement exactly what the code changes bring about, but without all that hassle. With one click, you can switch Dark Mode on and off in WhatsApp Web.

Download: Dark WhatsApp Web for Chrome (Free)

You Can Also Use WhatsApp Web on Apple Devices

All of these tips and tricks require you to use WhatsApp Web on a desktop computer, ideally through the Google Chrome web browser.

However, you can also trick your Apple devices into working with WhatsApp Web, so here’s how to use WhatsApp Web on your iPad.

If the coronavirus is really airborne, we might be fighting it the wrong way



This was the week airborne transmission became a big deal in the public discussion about covid-19. Over 200 scientists from around the world cosigned a letter to the World Health Organization urging it to take seriously the growing evidence that the coronavirus can be transmitted through the air. WHO stopped short of redefining SARS-CoV-2 (the virus that causes covid-19) as airborne but did acknowledge that more research is “urgently needed to investigate such instances and assess their significance for transmission of COVID-19.”

“I honestly don’t know what people are waiting for,” says microbiologist Chad Roy of Tulane University in the US. “It doesn’t take WHO coming out to make a proclamation that it’s airborne for us to appreciate this is an airborne disease. I don’t know how much clearer it needs to be in terms of scientific evidence.” 

So what does “airborne” really mean in this context? It’s basically an issue of size. We’re pretty sure that SARS-CoV-2 is spread through tiny droplets that contain viral particles capable of leading to an infection. For a virus to be airborne, however, means a few different things, depending on the expert you’re talking to. Typically it means it can spread via inhalation over long distances, perhaps even through different rooms, of small particles known as aerosols.

“That’s why when you ask some of the professionals if the virus is airborne, they’ll say it’s not, because we’re not seeing transmission over those sorts of distances,” says Lisa Brosseau, a retired professor of public health who still consults for businesses and organizations.

There is also some debate on what we mean by “aerosol.” The droplets that carry viral particles through the air can come in all sorts of sizes, but while the larger ones will drop quickly to the ground or other surfaces, the smaller ones (just a few microns across) can linger in the air for a while, giving them a chance to be inhaled. The word is mostly used to describe these smaller particles, although Brosseau would prefer the term “aerosol transmission” to cover the entire gamut of inhalable viral particles being expelled into the air—large and small alike. 

If SARS-CoV-2 is airborne, it’s far from the only disease. Measles is notorious for being able to last in the air for up to two hours. Tuberculosis, though a bacterium, can be airborne for six hours, and Brosseau suggests that coronavirus superspreaders (people who seem to eject a larger amount of the virus than others) disseminate the virus in patterns that recall the infectiousness of tuberculosis.

The evidence that this type of transmission is happening with SARS-CoV-2  arguably already exists. Several big studies point to airborne transmission of the virus as a major route for the spread of covid-19. Other studies have suggested the virus can remain in aerosolized droplets for hours. One new study led by Roy and his team at Tulane shows that infectious aerosolized particles of SARS-CoV-2 could actually linger in the air for up to 16 hours, and maintain infectivity much longer than MERS and SARS-CoV-1 (the other big coronaviruses to emerge this century). 

We still don’t know what gives SARS-CoV-2 this airborne edge. “But it may be one reason this is a pandemic, and not simply a small outbreak like any other coronavirus,” says Roy. 

How to stay safe

Whether the virus is airborne isn’t simply a scientific question. If it is, it could mean that in places where the virus has not been properly contained (e.g., the US), the economy needs to be reopened more slowly, under tighter regulations that reinforce current health practices as well as introducing improved ones. Our current tactics for stopping the spread won’t be enough.

Roy would like to see aggressive mandates on strict mask use for anyone leaving home. “This virus sheds like crazy,” he says. “Masking can do an incredible amount in breaking transmission. I think anything that can promote the use of masking, to stop the production of aerosols in the environment, would be helpful.” 

Brosseau, however, says that though masks can limit the spread of larger particles, they are less helpful for smaller ones, especially if they fit only loosely. “I wish we would stop relying on the idea that face coverings are going to solve everything and help flatten the curve,” she says. “It’s magical thinking—it’s not going to happen.” For masks to really make a difference, they would need to be worn all the time, even around family.

Brosseau does believe the evidence is trending toward the conclusion that airborne transmission is “the primary and possibly most important mode of transmission for SARS-CoV-2.” She says, “I think the amount of time and effort devoted to sanitizing every single surface over and over and over again has been a huge waste of time. We don’t need to worry so much about cleaning every single surface we touch.” Instead, the focus should be on other factors, like where we spend our time.

Crowded spaces

One of the biggest questions we still have about covid-19 is how much of a viral load is needed to cause infection. The answer changes if we think it is aerosols that we need to worry about. Smaller particles won’t carry as large a viral load as bigger ones, but because they can linger in the air for much longer, it may not matter—they’ll build up in larger concentrations and get distributed more widely the longer an infected person is around to expel aerosolized virus. 

The more people you have coming in and out of an indoor space, the more likely it is that someone who is infected will show up. The longer those infected individuals spend in that space, the higher the concentration of virus in the air over time. This is particularly bad news for spaces where people congregate for hours on end, like restaurants, bars, offices, classrooms, and churches. 

Airborne transmission doesn’t necessarily mean these places must stay closed (although that would be ideal). But wiping down surfaces with disinfectant, and having everyone wear masks, won’t be enough. To safely reopen, these spots will not just need to reduce the number of people allowed inside at any given moment; they will also need to reduce the amount of time those people spend there. Increasing social distancing beyond six feet would also help keep people safer. 

Ventilation needs to be a higher priority too. This is going to be a big problem for older buildings that usually have worse ventilation systems, and areas with a lot of those might need to remain closed for much longer. The impact of asymptomatic spread (transmission by people who don’t feel ill) and superspreaders only compounds the problem even further. But research conducted by the US Department of Homeland Security has shown that in the presence of UV light, aerosolized particles of the size the Tulane researchers studied would disappear in less than a minute. A number of businesses have begun deploying UV-armed robots to disinfect hospital rooms, shopping malls, stores, public transit stations, and more.

For many places, considerable delays in economic reopening might ultimately be the price of getting the virus under control. Otherwise the kind of thing that happened when a single open bar in Michigan led to an outbreak of more than 170 new cases could become commonplace. 

For Brosseau, the best strategy is simply to behave as we did in the early days of lockdown—stay home, and avoid coming into contact with anyone you don’t live with. And if you have to leave home, she says, “all I can say is spend as little time as possible in an enclosed space, in an area that’s well ventilated, with as few people as possible.”

(Re)Making a ColecoVision



[Leaded Solder] found some ColecoVision game cartridges at a flea market, and like most of us would, thought, “I’ll build a ColecoVision console from scratch to play them!” Well, maybe most of us would think of that, but not actually do it. He did and you can read about the results in great detail since he wrote up two posts, one covering the design and one covering the construction.

The ColecoVision was a game console that famously could be expanded into a nice — for its day — personal computer. It even had a daisy wheel printer in that configuration. However, in either configuration, the game console was the brains of the operation. According to [Leaded Solder] the price of a unit in working order is high even though over 2 million were made because of several design problems that make them less likely to survive the decades. Rather than repair and modify an original unit, it was cheaper and much more educational to build new.

The design goal was to use composite video, a single power supply, and reduce the size of the board, mainly by using surface mount parts where possible. [Leaded Solder] admits he didn’t fully understand how address and data buses worked in a system like this when starting this project, and he documents what he learned and winds up with a pretty succinct summary of bus operation. We’d argue that the statement, “…only one chip on a bus is supposed to be enabled at a time…” is a little misleading, however. Two chips are enabled at a time, one writer and one reader. In addition, it isn’t uncommon to have several devices read at the same time (for example, some CPUs have two copies of each register). But that’s a nitpick, especially in the context of the Z80 CPU used here.

By the time the PCBs arrived, the total price tag was up to just over $68 Canadian. We remember scrambling EPROMS on circuit boards to make layout easier. After all, you don’t care that location 0 and 1 in your EPROM are actually in adjacent cells. You just care that when you ask for one, you get it. The ColecoVision apparently did the same thing with its video and audio chips. The data bus runs in reverse. That is the Z80’s D0 pin connects to D7 and D7 connects to D0. Unfortunately, the original PCB didn’t take that into account for the sound chip, so a new board revision solved that problem.

The posts are pretty blunt about mistakes made and maybe we can all learn a little from reading about them. For example, subtle differences in footprints caused several problems with the first two versions of the board. By the end, there were 6 spins of the board. Luckily, PC boards are cheaper than they used to be.

Even so, there are still some controller issues, but we have no doubt he’ll solve it and tell us about it when he does. If you’ve ever tackled a project of this size, you are probably all too familiar with the process of debugging a new board. But most of us don’t document it to this extent. If you ever wanted to watch over someone’s shoulder doing a new design like this, you’ll want to read these posts.

Maybe before making boards, a breadboard would have helped. The idea of converting a game console into a PC wasn’t just for the ColecoVision and Adam (the ColecoVision’s computer personality). There were some attempts to do the same with the popular Atari 2600.
