You can use the LMB key on your keyboard to click and drag objects around the screen. It’s also utilized for opening files and highlighting text. But it’s not as common as media keys. Since this key is limited to use on specialized keyboards, its purpose is often questioned.
What Is The LMB Key On A Keyboard?
One outdated standard keyboard key that is still in use today is the LMB (left mouse button). Any button on a computer mouse, including the left half of the device, is referred to as a “left mouse button.”
A standard mouse consists of four buttons: two for up/down and left/right movement; one for clicking; and a fourth button, referred to as “middle,” which lets you alternate between clicking once in left- or right-click mode.
The middle mouse button, or MMB for short, is sometimes confused with a trackpad or scroll wheel. But let’s clear up any confusion—they are distinct from one another and serve various goals in different contexts!
The Left Mouse Button (LMB) on your keyboard allows you to do a left click without the need for a mouse. The enter button on your keyboard serves the same purpose as this button.
Should you utilize Windows’ Mouse Keys feature, this button may be extremely helpful to you. Additionally, the LMB key is useful if you use a trackball or a keyboard with an integrated touchpad.
Why Is the LMB Key Used?
The LMB can be used in several ways:
You can click on anything on your screen by moving the mouse pointer to the desired location while holding down the left mouse button. When the LMB reaches its desired position, it will release its grip (or specified area).
It will just move on without making any clicks or selections if there is nothing there. Not only may you use this way to click objects on the screen, but many programs also provide access to users and non-users equally by holding down the corresponding mouse buttons simultaneously while employing a modifier key:
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
Numpad keys can be used to control the mouse cursor, thus you can click with them as well, thanks to Windows’ previously mentioned Mouse Keys feature.
However, it can be very difficult to use the feature’s mouse-click functionality. This is because you have to press a different key each time you need to swap between different mouse buttons.
To push the Left Mouse Button and the Right Mouse Button consecutively using mouse keys, for example, you would need to press the Numpad’s “5” key, the Minus (-) symbol, and then the “5” key once more.
The LMB key on the keyboard is useful in this scenario since it allows you to always start the left-click operation with a single key press.
Keyboard with Touchpad
On keyboards with touchpads, LMB keys are present to provide complete mouse functionality on the keyboard. This functions pretty much like the touchpad on a laptop.
Here, the LMB key is usually a button located directly beneath the touchpad or a clickable area of the touchpad.
If your keyboard has this capability, you don’t need an external mouse because this key is the same as the LMB key on a mouse.
Keyboard with Trackball
The LMB key is present on both the touchpad and trackball keyboards. A trackball added to a keyboard would be useless without this key.
A keyboard with a trackball usually has the LMB button next to the trackball, like that of a standard trackball mouse.

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
The left side of the keyboard is normally home to the LMB (left-middle-button). Because it looks similar a fingerprint, it is also referred to as a “touchpad” or “fingerprint.” Though it resembles one, it’s not quite the same as a fingerprint!
You may adjust the amount of pressure your computer applies when you click on something by pressing LMB. Thus, if you wish to rearrange text within 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; Release LMB when all three fingers are held down once more. In this manner, every finger will travel independently, preventing any inadvertent keystrokes!
What is Different from MMB and RMB?
LMB is a keyboard key that’s used for dragging, clicking, and frequently opening files. MMB refers to the scroll bar that is seen on the edge of your screen. Depending on what you click with the RMB (right mouse button), it can perform a variety of tasks.
Right-clicking within an application, such as Word, Excel, or PowerPoint, will select the item or text that your cursor is now over.
When utilizing a web browser like Internet Explorer or Firefox, right-clicking will display options such as the Back and Forward buttons. This feature enables users to quickly navigate through pages without repeatedly pressing F5. Additionally, users can access various settings within these browsers, such as disabling pop-up advertisements.
Using the RMB and LMB together, Highlight the text
You can click, drag, and open files with the LMB a lot. When using a mouse and keyboard for the first time, it’s easy to find because it’s usually situated to the left of the spacebar.
The LMB is located under or, in certain cases, slightly above the number pad on computers. If your laptop lacks a number pad, however, search the upper row of keys for an icon that resembles two arrows pointing in the same direction.
Instead of pressing the arrow buttons straight into their designated positions, which could cause inadvertent typing, you should lightly touch down on them with your fingertips to move the cursor to this location.
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 Middle Mouse Button, or MMB key, is the last of the three keys.
Unlike LMB and RMB, the MMB key may not be on every keyboard that contains the LMB and RMB keys, as its functionality isn’t as vital as these keys.
Is the LMB Key on Every Keyboard?
Telling the reality, we have no idea if the LMB key appears on any keyboard ever made. All keyboards, wired or wireless, do, however, have the handy F10 shortcut key in addition to the SHIFT key.
Advantages of Having a Keyboard with an LMB Key
If your workspace is too small to fit your desktop computer or laptop, it shouldn’t come as a surprise that there isn’t enough area for you to work. This could make it harder to scroll and utilize a peripheral mouse. In some situations, the left mouse button might be crucial, and it can prove to be a useful and effective solution to this problem.
If your keyboard has an LMB key, you can easily work on numerous multimedia apps while relaxing on your couch or even in bed. This gives you a great deal of versatility, and whether or not you choose to use it is totally up to you.
The most times you’ll be grateful to have a left mouse button on your keyboard are when it fails or when you forget it at work and have a project or report deadline the following day.
The mouse on your computer will become your best friend if it becomes broken or lost forever and you have to wait a few weeks for a replacement to come in. In circumstances like this, where most people have no other option, these buttons are essential.
Disadvantages of Having a Keyboard with an LMB Key
You shouldn’t put your mouse away right away, even though the LMB button is really useful. The LMB key has significant disadvantages as well, which you may notice after using it frequently despite all of its advantages.
Below is a list of a few of the more common ones:
Using the LMB key will be quite difficult if the touchpad sensor chooses to go bad.
The LMB key on a keyboard is not as precise or productive as using an external mouse, according to multiple studies.
Certain online video games may not be compatible with the keyboard’s left mouse button. Doing extensive research will help you avoid this, as it may be a deal-breaker for die-hard players.
It’s possible that some expensive design and 3D modeling programs, such as Fusion 360, prohibit using the keyboard’s LMB key.
Even though the LMB key isn’t present on many keyboards, it is undoubtedly useful in a variety of scenarios. It becomes an excellent substitute, especially if you want to take a vacation from using your external mouse.
We hope that your education on the LMB and its applications has been enjoyable. Recall that this button can be found on a variety of other devices besides computer keyboards! Please feel free to ask any queries you may have in the comments section.
