LMB Key On Keyboard: Everything You Should Know

You might be excused for thinking that keyboards are primarily used for typing, as do the majority of people.

Although typing is undoubtedly their primary use, keyboards have advanced to the point that they now feature extra keys that have additional uses.

However, if your mouse or trackpad isn’t working, you might be curious about what the LMB key does and how to utilize it. The LMB key can serve you as a helpful button if you learn how to perform all of its functions.

The LMB key is a key on your keyboard that you can use to click and drag items on the screen. It’s also used to highlight text and open files. However, it’s not as prevalent as media keys. The purpose of this key is frequently questioned because it is only seen on specialized keyboards.

You might be wondering what LMB on a keyboard stands for. Where is it located, and what does it do? We would like you to know you’ve come to just the right place. Let’s get started.

What Is the LMB Key on a Keyboard?

The LMB (left mouse button) is an old standard keyboard key that’s still used today. The definition of “left-mouse button” is simple: it’s any button on a computer mouse, including its left half.

A typical mouse has four buttons: two for moving left/right and up/down; one for clicking; and another one called “middle” that allows you to switch between left-click mode (clicking once) or right-click mode (clicking twice).

LMB is often confused with the MMB (middle mouse button), also called a scroll wheel or trackpad. However, they’re different and have different purposes in different situations so let’s clear up some confusion!

The LMB button on your keyboard is the Left Mouse Button, which lets you do a left-click action without requiring a mouse. This button has the same function as the enter button on your keyboard.

If you are one of the users of the Mouse Keys feature in Windows, then this button could prove especially useful to you. Also, the LMB key comes in handy if you use a keyboard that has a touchpad built into it or a trackball.

What Is the LMB Key Used For?

There are several ways you can use the LMB:

To click something on your screen — this is done by holding down the left mouse button and then moving it to where you want to click. The LMB will let go when it reaches its target location (or selected area).

If there isn’t anything in that spot, it will just move on without making any clicks or selections. In addition to being able to click things around the screen using this method, many programs allow users (and non-users) alike access by using a modifier key while holding down their respective mouse buttons at once:

Ctrl + Left Mouse Button = Click; Ctrl + Right Mouse Button = Double Click; Alt + Left Mouse Button = Dragging an object around with one hand while simultaneously moving another object with another hand.

Using Mouse Keys

The previously stated Mouse Keys function in Windows enables you to control the mouse cursor using Numpad keys, which means you can also perform click actions with these keys.

However, using the feature’s capability to execute mouse clicks can be quite cumbersome. This is because every time you want to switch between various mouse buttons, you have to hit a separate key.

For instance, pressing the “5” key on the Numpad, the Minus (-) symbol, and then the “5” key once again would be necessary to push the Left Mouse Button and the Right Mouse Button consecutively using Mouse Keys.

In this situation, having a dedicated LMB key on the keyboard is helpful since it enables you to always initiate the left-click operation with a single key press.

Keyboard with Touchpad

LMB keys are included on keyboards with touchpads to provide full mouse capability on the keyboard. This works in much the same way as a laptop’s touchpad.

In this instance, the LMB key is typically a button just below the touchpad or a clickable portion of the touchpad.

There is no need for an external mouse if you have a keyboard with this feature because this key is identical to the LMB key on a mouse.

Keyboard with Trackball

Keyboards with trackballs have an LMB key, just like keyboards with touchpads. Not having this key would make adding a trackball to a keyboard pointless.

Similar to how a typical trackball mouse is made, the LMB button on a keyboard with a trackball is typically placed beside the trackball itself.

Keyboard with TrackPoint

The LMB key is also included on keyboards with a TrackPoint (the red dot that is frequently found on Lenovo laptop keyboards), as the TrackPoint was designed to provide all the functions of a mouse.

Since there isn’t room for it to be placed around the TrackPoint, the LMB key is situated at the bottom of the keyboard.

Where Is LMB Located on Various Types of Keyboards

LMB (left-middle-button) is typically located on the left side of the keyboard. It’s also known as a “touchpad” or “fingerprint” because it looks like a fingerprint. Despite this similarity, it’s not exactly a fingerprint!

When you press LMB, you’re telling your computer how much pressure to apply when you click on something. So if you want to move text around in a Word document.

For example, press LMB and drag across some text with one hand while holding down SHIFT with your other hand so that all three fingers are touching at once; then release LMB when all three are pressed down again. That way each finger will move independently—and with this, you can avoid any accidental keystrokes!

How Does It Differ From MMB and RMB?

LMB is a key on the keyboard used for clicking, dragging, and often opening files. MMB is the scroll bar that you see along the side of your screen. RMB (Right Mouse Button) has different functions depending upon what you are clicking on when using it:

If your cursor is hovering over an object or text inside an app like Word, Excel, or PowerPoint then right-clicking will select that object or text within that app.

If you are using a web browser such as Internet Explorer or Firefox then right-clicking will bring up options like Back and Forward buttons which allow users to navigate through pages quickly without having to do something like pressing F5 every time they want to access another page; it also allows users access various settings within these browsers such as turning off pop ups.

LMB Is Used With the RMB To Highlight Text

The LMB is used for clicking, dragging, and often for opening files. It’s located to the left of the spacebar on most keyboards, which makes it easy to find if you’re just starting out with using your mouse and keyboard.

On laptops, the LMB can be found under your number pad or just above it (on some models). If you don’t have a number pad on your laptop though, then look for an icon that looks like two arrows pointing toward each other in the top row of keys.

This will be where the cursor will move when you press down gently on those arrow buttons with your fingertips instead of pressing them directly into their respective positions (which would result in accidental typing).

The LMB or left-mouse button can be called a selection button, or simply a left-click button. It is used by many programs and applications to do things like move files, open files, folders, etc. But it’s also used in games to control the camera or your character’s movement.

The LMB can also be found on various types of keyboards including those with numeric keypads (like laptops), and gaming keyboards that have extra buttons for additional functions such as this Logitech keyboard.

What Is the MMB Key on Your Keyboard?

The last of the three keys is the MMB key, which stands for Middle Mouse Button.

Unlike LMB and RMB, the MMB key may not be on every keyboard which contains the LMB and RMB keys, as its functionality isn’t as vital as these keys.

Do All Keyboards Have the LMB Key?

To be quite honest, we don’t know if the LMB key is present on every keyboard in existence. However, we do know that every keyboard, wireless or wired, includes the useful F10 shortcut key in addition to the SHIFT key.

Benefits of Having an LMB Key on Your Keyboard

It should come as no surprise that there isn’t enough room for you to work if your workplace is too small to accommodate your desktop or laptop. A peripheral mouse may become difficult to scroll and maneuver as a result. The left mouse button can be key in certain scenarios and can turn out to be a practical and efficient answer to this issue.

You can simply work on various multimedia apps while unwinding on your sofa or even in bed if your keyboard has an LMB key. You have a lot of flexibility here, and it is entirely up to you whether you choose to take advantage of it or not.

When your mouse breaks down or when you accidentally leave it at work but have a deadline for a project or report the next day, you’ll appreciate having a left mouse button on your keyboard the most.

If you lose or permanently damage your mouse and have to wait a few weeks for a replacement to arrive, your computer’s LMB will quickly become your closest buddy. These buttons are very necessary for situations like these when there is no other choice for the majority of people.

Disadvantages of Having an LMB Key on Your Keyboard

Despite the LMB button being quite handy, you shouldn’t immediately put away your mouse. Despite all of its benefits, the LMB key does have certain drawbacks that may become apparent to you after frequent use. A few of the most typical are listed below:

Using the LMB key will be quite difficult if the touchpad sensor chooses to go bad.

According to several studies, using an external mouse is more accurate and productive than using the LMB key on a keyboard.

The left mouse button on the keyboard might not work with some online video games. For avid gamers this is a potential deal-breaker, so be sure to conduct thorough research to prevent it.

When using the LMB key, some tasks could take noticeably longer than they would with an external mouse or might not be possible at all.

Some high-end design and 3D modeling applications, like Fusion 360, might not allow pressing the LMB key on a keyboard.

Conclusion

There is no doubt that the LMB key has its benefits in several situations, even though you won’t find it on many keyboards. Particularly if you would like to take a break from using your external mouse, then it comes up as a good alternative.

We hope you’ve enjoyed learning about the LMB and its uses. Remember, this button is not just used with computer keyboards but in many other types of devices too! If you have any questions, then feel free to leave them in the comments. We’ll get back to you as soon as we can!
