Mouse buttons are physical switches on a computer mouse that allow you to interact with your computer’s graphical user interface (GUI). While some very early mice featured only one button, the standard computer mouse has evolved to include several standard buttons, scroll wheels, and, in many cases, programmable extra buttons. The Standard Mouse Buttons 1. Left Mouse Button (Left-Click)
What it does: This is your primary “action” button. It is used to select, drag, highlight text, and open programs or files. Actions: Single-click: Selects an item or follows a web link.
Double-click: Quickly pressing this button twice opens a file or launches an application.
Click and drag: Pressing and holding the button allows you to highlight text or move files around on your desktop.
Note: Left-handed users can swap the functions of the left and right buttons in their operating system’s settings (e.g., in Windows via Microsoft Mouse Settings). 2. Right Mouse Button (Right-Click)
What it does: This is the context button. When clicked over a specific icon, link, or highlighted text, it opens a drop-down menu with options tailored to that specific item (like copying, pasting, deleting, or viewing properties). 3. Middle Mouse Button & Scroll Wheel
What it does: Positioned between the left and right buttons, the scroll wheel is used to navigate up and down on a webpage or document. Actions: Scrolling: Rotating the wheel moves the page.
Middle-click: Pressing down directly on the wheel acts as a third button. In web browsers, middle-clicking a link opens it in a new tab, and middle-clicking a tab will close it. Extra Buttons & Advanced Mice
