You’re staring at your laptop. There’s that big, chunky button on the right side. On a Mac, it says "return." On a PC, it usually says "enter." Sometimes it’s just a weird hooked arrow pointing to the left. Honestly, most of us just mash it without thinking whenever we finish a sentence or want to send a risky text. But if you’ve ever wondered what is the return key on keyboard setups specifically meant to do—and why it has two different names—you’re falling down a rabbit hole of typewriter history and computer architecture. It’s not just the "go" button. It’s a relic of mechanical levers and ink-stained fingers.
Back in the day, before we had glowing screens, we had typewriters. When you reached the end of a line, you had to physically shove a carriage back to the start of the page. This was the "Carriage Return." That’s where the name comes from. It didn't just move you to a new line; it reset the entire mechanism.

The Return Key vs. The Enter Key: They Aren't Twins
People use these terms interchangeably. They shouldn't. While they often perform the same task in a modern web browser, they have distinct identities in the world of computing. Think of it like this: the Return key is about the cursor, while the Enter key is about the data.
If you’re working in a word processor like Microsoft Word or Google Docs, hitting the return key tells the computer you’re done with this line and want to start a new paragraph. It originates from the ASCII code for "Carriage Return" (CR). On the other hand, the Enter key—traditionally found on the numeric keypad of full-sized keyboards—tells the system to "enter" the information you just typed into a form or a cell. It’s an execution command.
In some high-end software, like Adobe InDesign or certain programming environments, these two keys actually do different things. Hitting "Return" might start a new paragraph, but hitting "Enter" (on the keypad) might jump you to the next column or text frame. If you’re a coder, you know that \r and (newline) are two different beasts. One moves the "print head" back to the start, and the other moves it down.
Does it matter which one you use?
For 99% of people? No. Modern operating systems like Windows 11 and macOS are smart enough to guess what you want. You press the big button, and the email sends. But for power users and vintage tech enthusiasts, the distinction is a badge of honor. Apple is the main holdout here, consistently labeling the main key as "return" on their MacBooks, while most Windows laptops have fully pivoted to "Enter."
Why the Shape of the Return Key Changes Everything
Ever bought a laptop and felt like you were typing with mittens on? You probably switched between an ANSI and an ISO layout.
The North American standard (ANSI) features a rectangular, horizontal return key. It’s wide. It’s easy to hit with your pinky. But go over to Europe or the UK (ISO layout), and you’ll find a massive, L-shaped monstrosity. This vertical "ISO Return" is iconic. Some people swear by it because it’s almost impossible to miss. Others hate it because it pushes the backslash key into a weird spot.
It’s a layout war that has raged since the 1980s.
- ANSI (American National Standards Institute): The slim, horizontal bar. Popular in the US, Canada, and parts of Asia.
- ISO (International Organization for Standardization): The "tall" key. Standard in the UK, Germany, and most of Europe.
- Big-Ass Enter: Yes, that is the technical term used by keyboard enthusiasts for the giant L-shaped keys that take up two rows and are wider than a standard key. You’ll mostly find these on vintage mechanical keyboards from companies like Northgate or old IBM clones.
What Happens When You Press Return?
It’s not just magic. When you hit that key, the keyboard controller sends a specific "scancode" to your computer. The operating system looks at that code and says, "Oh, they want to submit this."
In a command-line interface (CLI) like Terminal or Command Prompt, the return key is the trigger. You type sudo apt-get update and nothing happens until you commit. That’s the return key acting as the "executioner." In a chat app like Slack or Discord, hitting return sends the message. But—and this is a pro tip—if you hold Shift + Return, you get a new line without sending the message.
It’s all about the software’s "event listener." The programmers decide what that keypress triggers. Sometimes it’s a keydown event, sometimes a keypress. If you’re frustrated that your favorite app sends messages instead of making new lines, blame the UI designer, not the keyboard.
Common Myths About the Return Key
There is a weird amount of misinformation about this specific piece of plastic. Some people think the Return key is "faster" than clicking a "Submit" button. Technically, yes, because your hands are already on the home row. But in terms of processing speed? The computer doesn't care.
Another myth: "The Return key is the same as the Space bar in some games."
Sort of, but not really. While many games allow you to use Return to skip cutscenes, its primary role in gaming is opening the chat box. In the heat of a League of Legends or Counter-Strike match, hitting Return is how you tell your teammates they’re doing a great job (or, more likely, the opposite).
"The return key is the finality of a thought. In the analog days, it was a physical reset. Today, it's a digital handshake." — This is how old-school typesetters used to describe the transition to digital.
Troubleshooting a Broken Return Key
What if yours stops working? It’s the worst. Since the return key is one of the most used keys alongside the Space bar and 'E', it’s often the first to go.

If you have a mechanical keyboard, it’s usually a "stabilizer" issue. Because the key is so wide, it needs extra support bars to keep it from wobbling. If the key feels mushy or stuck, a bit of compressed air or some dielectric grease on the stabilizers usually fixes it. On a laptop? You might be looking at a debris issue. Butterfly switches (looking at you, 2016-2019 MacBooks) were notorious for failing if a single crumb got under the return key.
If the key is physically fine but isn't responding, check your "Sticky Keys" settings in Windows or macOS Accessibility. Sometimes software locks it out.
The Evolution: From Typewriters to Virtual Glass
We’re moving toward a world without physical keys. On your iPhone or Android, the "return" key changes its name based on what you’re doing. If you're in Safari, it says "Go." If you're in a text message, it says "Send." If you're in a Note, it’s a return arrow.
This is the ultimate form of the return key. It’s contextual. It doesn't need to be one thing because it can be everything. Yet, even on a flat glass screen, we still look for that bottom-right corner. The muscle memory is baked into our DNA at this point.
Why you should care about your keyboard layout
If you’re a writer, a coder, or just someone who spends eight hours a day in front of a screen, the return key is your most frequent interaction with the digital world. Choosing a keyboard with a return key that feels "right"—whether that’s a clicky mechanical switch or a short-travel membrane—is actually a huge ergonomic win.
If you're constantly overreaching or hitting the backslash key by mistake, your layout is wrong for your hands. Don't fight it. Switch.
Practical Steps to Master Your Keyboard
Don't just be a casual typer. Use the return key like a power user.
- Learn the "Alt + Enter" trick: In Excel, hitting Return moves you to the next cell. Hitting
Alt + Enterlets you start a new line inside the same cell. It’s a lifesaver. - Command + Return: In many email clients (like Gmail or Outlook), hitting
Cmd + Return(Mac) orCtrl + Enter(PC) sends the email instantly. Stop mousing over to the "Send" button. - Remapping: If you hate where your return key is, use software like PowerToys (Windows) or Karabiner-Elements (Mac) to remap a different key to function as a Return. Some people map their "Caps Lock" to "Return" because it’s easier for the left hand to reach.
- Clean your stabilizers: Every six months, pop that big key off (carefully!) and wipe away the dust. It’s a magnet for hair and crumbs.
The return key is basically the "period" at the end of a sentence for your entire digital life. It’s the final word. It’s the "make it happen" button. Understanding that it’s a bridge between the mechanical past and the touch-screen future makes those thousands of daily clicks feel a little more significant.

Stop thinking of it as just a button. It’s the command center. Whether you're finishing a line of code or just firing off a "k" to a long paragraph, you're using a piece of history. Keep it clean, know your layout, and maybe stop hitting it so hard when you're angry. Your stabilizers will thank you.
To optimize your daily workflow, start by auditing your "mis-strikes." If you find yourself hitting the key above the return key more than five times a day, it’s time to look into a different keyboard standard, like switching from ISO to ANSI. You can also experiment with "layers" in programmable mechanical keyboards to put a return function right under your thumb for maximum efficiency.
