The term "dblclick" refers to the action of pressing a mouse button twice in quick succession. This action is commonly used in computer interfaces to open files, launch applications, or select items. It is a standard method for interacting with graphical user interfaces (GUIs) in operating systems like Windows and macOS. In programming, "dblclick" can also refer to an event that is triggered when a user performs a double-click. Developers can use this event in languages like JavaScript to create interactive web applications, allowing for enhanced user experiences by responding to user actions effectively.
