LMB means Left Mouse Button, which is the left button on your mouse. It’s the click you make dozens of times a minute without even thinking about it. If a game or tutorial asks you to press LMB, it’s simply asking you to left-click.
This English term comes up often in video games and computer tutorials. You'll also come across it in software such as Blender, where the left mouse button is used to select and manipulate objects.
What does the LMB key mean?
LMB is the acronym for Left Mouse Button. In French, this means the left mouse button. It's the click you use dozens of times a minute, often without even thinking about it.
When a program or guide asks you to use the LMB, it’s simply asking you to left-click. Depending on the context, the LMB performs a simple or complex action: selecting an item, confirming a choice, or interacting with an interface. It’s the basic means of interaction between you and the screen.
The mouse has several buttons, and the left mouse button (LMB) is the one used most often. You'll also come across the terms RMB for the right button and MMB for the middle button. Understanding these three abbreviations will allow you to follow any tutorial without hesitation:
- LMB : Left mouse button, to select and click.
- RMB : Right-click to open a context menu.
- MMB : the middle button—often the scroll wheel—for navigation.
How do you click the left mouse button with your mouse?
The key LMB is the left button on your mouse. To use it, place your index finger on it and press: that's a simple left-click.
- On a standard mouse, the left button is on the left, under the index finger of your right hand.
- On a laptop, tap the left side of the trackpad to perform the same command.
With this left button, you can perform several types of clicks:
- the single click : Select an object, image, or link in an interface.
- Double-clicking: Open a file, folder, or application.
- Click and hold (drag and drop): Keep the left mouse button pressed to move an object on the screen.
As the keys on a keyboard, the LMB helps you work more efficiently on your computer. In video games, it's often used to shoot, select an option, or interact with an object in the environment.
When to use the LMB key?
the left mouse button is used for almost everything you do on a daily basis. Here are the three main uses of the LMB:
- Single click: The basic action. You click and then quickly release the left mouse button to activate or select an item in an interface.
- Double-click: two quick, consecutive clicks. This usually opens a file, an application, or a web page.
- Click and drag : Hold down the left mouse button while moving the mouse. This allows you to move objects or select text.
In a browser such as Google Chrome or on a social media platform such as Facebook, the LMB is the command you use to like, navigate, open a link, or interact with a website's interface.
The left mouse button is the most commonly used of the three buttons on your mouse. The other two are the right mouse button on the right, and the MMB in the center, which is usually linked to the scroll wheel. The MMB is mainly used to move the view, rotate, or zoom in 3D modeling software such as Blender.
In Blender, the preferences let you enable the “emulate 3-button mouse” option. Even without a middle mouse button, the software will then act as if you had a full three-button mouse. You can also combine the left mouse button with the Shift to select multiple objects at the same time in the interface.
In video games, proper use of the left mouse button often makes all the difference in terms of speed and accuracy.

Your explanations are clear and very useful. I already knew this, but your articles have helped me to understand the lmb key even better.
When I click on lmb, it moves my outline and I just click very quickly to go to my menue. It's the same thing: I move my table to the grocery shop simulator game and I can no longer place orders or fill my shelves and serve my customers.
