Definition - What does Right Click mean?
The right click or “right mouse button” command or control is related to the use of a conventional computer mouse, a major peripheral developed in combination with the personal computer since the 1980s. The right-click corresponds to the right button of the mouse — most mice have two buttons, one on the right, and one on the left.
Techopedia explains Right Click
The idea of a right-click is extremely useful in programming and design — in any kind of program that utilizes the mouse as a command device, right-click is a convenient way to refer to the programming of this type of command in an operating system, application or other project.
In general, a right-click user event is a “deeper level” event than a left click. In other words, the left click is used for top-level processes like menu navigation, with a right-click often being used for things like file or system research. For example, where a left click might be used to simply open a menu item or a file, the right-click event is often a “help needed” event or a method for displaying background information about that item.
